Ashley Greene left the gym laughing and chatting with a friend after an intense workout in LA today. The birthday girl celebrated her 24th in Las Vegas last weekend, and now she's back to following the strict fitness schedule Tracy Anderson personally choreographed for her. Ashley's been absent from the red carpets this award season, but at least one Twilight star may be on hand this weekend at the Oscars. According to show producer Bruce Cohen, "if you are a Twilight fan . . . For all of you Twi-Hards out there, we have a little surprise for you in our show on Sunday night . . . if you like those three films, I have three words for you: watch the Oscars." We'll be broadcasting LIVE from the red carpet so follow us on Twitter for breaking news and photos, and don't forget we're also giving away a Samsung TV, so be sure to fill out BuzzSugar's ballot for your chance to win!
