Jennifer Aniston wore a low-cut dress to attend LACMA's Art and Film Gala in LA last night. She was joined by fiancé Justin Theroux, and inside the bash, the couple met up with pals Drew Barrymore and Will Kopelman. The foursome posed for photos together and even hovered over Will's phone looking at pictures. It was Drew's first red carpet since giving birth to her daughter Olive last month, and she covered her postbaby body in a gown by Lanvin. Jennifer was back in front of the cameras after attending the star-studded CFDA/Vogue Fashion Fund runway show with Isla Fisher, Tobey Maguire, and January Jones on Thursday.
