With long hair or a mohawk, a clean-shaved face or a beard, there's no denying it: Zac Efron is a THG favorite.

This talented actor doesn't crave the spotlight outside of work, has remained in a committed relationship with Vanessa Hudgens - and is just so gosh darn adorable!

Usher turns 32 today and it isn't only fans of this hip hop artist who should send him their birthday wishes.

Anyone afflicted with a case of Bieber Fever must give thanks to this singer/producer for discovering the boy, the myth and the legend that is Justin Bieber.

Ready to send whatever the opposite of birthday wishes would be, THG readers?

Grating, publicity-hungry reality star Michaele Salahi turns 45 today. In celebration, Bravo actually aired the episode of The Real Housewives of D.C. last night in which this pathetic woman and her husband crashed a White House party.

Randy Quaid! Our man! Happy birthday, buddy. We'd invite you over to celebrate, but you'd probably squat at THG headquarters for weeks after, so ... rain check?

Just kidding. Not really. He and his wife were arrested for burglary at their old house. They also frequent inns and then peace out without paying. It's a little weird.

Lil Wayne celebrates his 28th birthday today in style. Rikers Island style.

As he sits in the New York jail, doing time for weapons charges, all is not lost. The rapper is releasing his eighth album, I Am Not a Human Being, today!

Heidi Montag marked her 24th plastic surgery birthday yesterday.

She and husband Spencer Pratt paid a visit to the zoo in Santa Barbara, Calif., and for a "divorcing couple," it sure looks like the gruesome twosome is happy.

Grammy-winning singer Amy Winehouse has made it to age 27. It's a feat we're a little surprised at to be honest, but in a good way. Happy birthday, Ames!

Seriously, if you had Wino in your office celebrity death pool (come on, you know there is one), you probably had pretty good odds. But we're glad you lost.
