So, how old do you think Justin Timberlake really is?

Justin Timberlake is celebrating the big 3-0 today.  But the celebrations may be a little low key as J-T rings in his new year.  Speaking on the red carpet at last night's Screen Actors Guild Awards, the pop superstar said he planned to spend his birthday "working."  Justin has been filming the movie "Now" over the past several weeks.  It's the latest in a growing list of film credits for the former 'N Sync and "Mickey Mouse Club" star who has received praise for his work in the Facebook-orgins movie "The Social Network."  The film is nominated for eight Academy Awards next month, but it was completely shut out of last night's SAG Awards. 

Timberlake also provided the voice for Boo-Boo Bear in last year's live-action animated feature "Yogi Bear" and will co-star with Woody Harrelson, Mila Kunis and Emma Stone in the upcoming comedy "Friends With Benefits," due out in July.
