Leonardo DiCaprio turns 35 today, and last night he celebrated in style with a few of his famous friends. RadarOnline reports that pals who showed up at trendy West Hollywood nightspot Villa included Kate Hudson, Lindsay Lohan, Hayden Panettiere, Kevin Connelly and Ryan Phillipe.

Wonder if the “Titanic” heartthrob has something more intimate planned for tonight? Enjoy your day, Leo!

Gwen Stefani and Gavin Rossdale celebrated his 42nd birthday with a quiet lunch at the posh restaurant Madeo in Beverly Hills. Gwen looked fabulous in skinny black pants and a flowing sheer top with a red bra peeking through.

Kourtney and Kim Kardashian met with family at Kate Mantilini restaurant in Beverly Hills for Kim’s 29th birthday lunch yesterday. Kim later had had a big birthday dinner at the newly-opened Phillipe Chow restaurant on Melrose in West Hollywood.

Reality star Kim Kardashian turned 29 today, but wasn’t happy about the prospect at first. Yesterday, she Twittered, “Why am I not excited about my birthday tomorrow…?” Maybe 29 is too close to 30?

But Kim had a change of heart today, as the greetings—and presents—began to some in. “Thank you so much for all of your birthday wishes. My bday keeps getting better and better!” One thing Kim won’t be getting for her birthday is baby clothes. The new issue of Life&Style claims Kim is expecting, but a friend told Us Weekly that the story’s not true. “No way!!! The article says she want a family one day after she’s married!” Hey, Kim—that’s something you can save for your big 3-0 next year.

“The Hills” star Heidi Montag was conspicuously absent from sis Holly’s birthday party at Hollywood hotspot Empire on Saturday, but not because she had pressing career business that evening. The more famous Montag was invited to the soiree, but refused to show because her sibling refused to pay for her presence!

A source dished to Fox News, “Holly was really wishing that her sister could just be a sister and stop by her birthday party, but Heidi only goes places if she is getting paid. I mean, this is her sister and she wouldn’t even show up without a fee. That’s disgusting.”

Yes, but not surprising from half of Speidi, Inc. Too bad Mr. and Mrs. Spencer Pratt didn’t make the bash, since another of their relatives could have used a ride home.

Former “Scrubs” actor Donald Faison and girlfriend Cacee Cobb were among the celebs who came out to help hair stylist Ken Paves celebrate his birthday at Beso Restaurant in Hollywood. Cacee used to be Jessica Simpson’s personal assistant.

Newly single Kim Kardashian was spotted hanging out with Jessica Simpson at the Ken Paves birthday bash at Beso Restaurant in Hollywood. Were they dishing the dirt on their exes?

Mario Lopez is always the life of the party, and he certainly seemed to be having a good time at the Ken Paves birthday bash at Beso Restaurant in Hollywood.

Hair stylist to the stars Ken Paves was the man of the hour as a host of celebs came out to help him celebrate his birthday in style at Beso Restaurant in Hollywood.

Eva Longoria Parker played hostess at her at Beso Restaurant in Hollywood as the stars came out to help hair stylist Ken Paves celebrate his birthday. The “Desperate Houswives” star is a longtime client of Paves.

Jessica Simpson couldn’t miss the birthday bash for her good friend and hair stylist Ken Paves at Beso Restaurant in Hollywood, but didn’t seem too happy to be there. The gallant Paves helped to escort his glum client past a coterie of paps to her car. Too bad he didn’t have time to give her a better ‘do before the party started.

Actress Jaime Pressly looked a bit glum for a girl who just got engaged. She spent her 32nd birthday grocery shopping in Newport Beach, CA, with her brand new fiancé, entertainment lawyer Simran Singh, and her adorable son Dezi James. Dezi’s dad is Jamie’s ex Eric Cubiche. If Jaime’s bummed over the cancellation of “My Name is Earl,” I don’t blame her.

Lindsay Lohan turns 23 today, but she probably already received her best present over the weekend—a big payout just for celebrating!

Page Six claims LiLo scored a whopping $70,000 for hosting an all-day “pre-celebration” pool party at the the MGM Grand’s Wet Republic in Las Vegas  on Saturday. What did the starlet do to earn it? Basically, she modeled five bathing suits and danced to Michael Jackson songs. Nice work!

Linds tried to capitalize on her 21st two years ago, but the scheduled bash at Las Vegas nightclub Pure was derailed by her trip to rehab following two arrests for DUI. She had to settle for a quiet beach party in Malibu (pictured) with family and friends.

If Lohan throws herself a bigger ‘do tonight, at least she’ll be able to pay for the booze. 

Newly-blonde Jessica Alba bought herself a scrap book on her 28th birthday in West Hollywood, CA. Is she planning to save mementos for Honor Marie?

Looking like she just rolled out of bed and surrounded by bodyguards, Katie Holmes was spotted in Huntington Beach, CA, Friday. Was she looking for a last-minute birthday present for Suri?

Tom and Katie’s little princess Suri Cruise had her third birthday yesterday, and she celebrated with a bash fit for royalty.

People reports Suri marked the occasion with a small group of family and friends at a princess-themed party, complete with a cake inspired by Belle from “Beauty and the Beast.” A source told People, “They just wanted to keep it small and make it fun for Suri and her friends.”

Since Katie was seen earlier this week visiting a West L.A. fertility clinic, could Suri be getting a little brother or sister in time for her next birthday?

Jessica Biel had her 27th birthday yesterday, and beau Justin Timberlake made it a day (and night) to remember in the Big Apple!

E! reports the photogenic pair shared a romantic dinner at Oak Room at the Plaza, then enjoyed Will Ferrell’s one-man show, “You’re Welcome America. A Final Night with George W. Bush.”

The dinner sounds great, but our last prez isn’t really what I’d want to be reminded of on my birthday. Hopefully, back in the privacy of their swanky new NYC apartment, Justin gave his lady some shiny goodies—like diamonds, maybe?

Jennifer Love Hewitt celebrated her 30th birthday this week by channeling Audrey Hepburn as Holly Golightly in “Breakfast at Tiffany’s.” Nice dress, nice bling, but I don’t think they had Starbucks back in Audrey’s day.

Pop beauty Rihanna is getting some need relaxation on the beaches of Mexico. The NY Daily News reports that the singer celebrated her 21st birthday with friends at a private beachside villa in Punta Mita.

Her bruises are healing but Rihanna’s troubles are hardly over. She still has to testify in the case against R&B star Chris Brown, who allegedly beat her up earlier this month. 

But for now, the songbird seems to be leaving her cares behind and trying to find peace for a little while.

Today is Paris Hilton’s 28th birthday, but the party started early, as the heiress and her sister Nicky got together with some friends at downtown Manhattan nightspot Club Butter.

Friends on hand to help Paris celebrate included former fiance Stavros Niarchos, Brandon Davis, Aubrey O’Day, and JC Chasez. I doubt this will be he end of the festivities—there has to be a bigger bash planned for tonight.
