Jennifer Aniston filmed a racy scene with Jason Sudeikis and Emma Roberts for We're the Millers in Wilmington, NC, today. She arrived on set in a blue tank, and once she was in front of the cameras the unbuttoned top revealed her bra and abs. Jennifer was also sporting a new accessory — a band on her left ring finger. Jennifer debuted the jewelry on Friday after becoming engaged to Justin Theroux earlier this month. Justin apparently popped the question on his 41st birthday in a teary proposal to his girlfriend of almost two years. He's since been spotted in NYC, where he was smiling big this weekend following the exciting news.
