Justin Timberlake said bye, bye, bye to another year at a very glam birthday bash!

The musician/actor/dreamboat celebrated his 32nd birthday on January 31 at a posh event at a new L.A. speakeasy called Varnish, according to Us Weekly.

"It was a dressed-up occasion," says a source, who reveals that JT's wife, Jessica Biel, was wearing an "amazing vintage Gucci dress that stunned." Would we expect anything less?

And what did Justin wear to his party? Why, a suit and tie, of course! Given his new single, "Suit and Tie," did you even have to ask?

Also in attendance were Chris Rock and Justin's longtime collaborator Timbaland.

"Everyone partied late," reveals the source. "Justin and Jess looked in love he was glad to have his crew around him."

Justin is going to have a busy couple of months ahead as he promotes his new, long-awaited album, which drops next month. Justin can be seen performing at the Grammys on February 10.

"A lot of music people in the house were talking about his record," says a different source about the birthday party. "He seemed genuinely excited about it and performing."

So who is going to have an amazing year? Guess what  it's gonna be Justin.
