Liberty Ross legs birthday kristen stewart scandal dress necklace

Liberty Ross dined at Spago last night with several friends, and not only did she look smokin' hot, but she looked genuinely happy.

After her ex-hubby Rupert Sanders was caught cheating with Kristen Stewart last year after working together on Snow White and the Huntsman, 34-year-old Liberty moved on with 60-year-old music mogul Jimmy Iovine, who she's been dating since January.

While Liberty smiled sweetly for photographers, she wasn't in the mood to chat, especially when asked if she wanted to wish Kristen a happy birthday, as she turned 23 yesterday.
