Birthday girl Vanessa Hudgens was spotted leaving the William Morris Agency in Beverly Hills. Today. Is that a new script in her hand? The Disney doll looked very chic in her black pants and colorful top.

“Grey’s Anatomy” star Katherine Heigl turns 31 today, and she has plenty to celebrate! This will be her first birthday with Naleigh, the baby girl Katherine and husband Josh Kelley adopted a few weeks ago. Little Naleigh also has a birthday this week—she turns one!

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!

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.

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?

Pink celebrated her 29th birthday last night at Madeo’s before heading over to Splash night club. From the looks of it, Pink’s none too happy about turning 29. Clad in black from head to toe, it looked like Pink was heading to a Wake rather than a party, albeit a sexy Wake. When will celebs learn that sheer black sans bra only add up to one thing. The above shot’s not too bad, but the shot of her back below says it all.
