Jennifer Aniston and Justin Theroux skipped doing the red carpet together -- she walked it solo --  but we found them inside at the 2012 Directors Guild of America Awards Saturday night, and they couldn't keep their hands off each other.

The romantic duo were hand-in-hand or with arms around each other the entire night.

Jennifer never looked happier, and dazzled in a black beaded strapless Dolce and Gabbana dress and Fred Leighton's diamond fringe pendant earrings and 13.0 carat rose-cut diamond and platinum ring.

Helen Mirren was there with her director hubby Taylor Hackford. George Clooney and his Descendents director Alexander Payne made it a guys night out.

Michelle Williams wore a Chanel couture gown, and sparkled in diamond jewels by Fred Leighton for Forevermark- diamond stud earrings  and a pair of diamond line and black cord bracelets.

Jon Favreau, Penelope Ann Miller, Amber Heard and Laura Dern were some of the other stars who turned out for the glamorous at the Hollywood & Highland Center.

George Clooney and Stacy Keibler aren't hiding from the cameras any more. They took their budding romance public Saturday night, stepping out for an event at the Toronto Film Festival.

Last night it was the premiere and after-party for director Alexander Payne's The Descendants, in which Clooney has a small role.

This was the third night in a row for Clooney-Keibler sightings but the first time they didn't take maneuvers to avoid the paparazzi cameras.  As RadarOnline.com previously reported, the pair was on the down-low for two events connected with Clooney's big new film, The Ides of March, which had its premiere at the Festival.

Clooney and the former Dancing with the Stars contestant have been quietly seeing each other since the late spring.

George's previous squeeze, Italian model and TV host Elisabetta Canalis makes her debut as a DWTS competitor when the new season of the ABC series premieres September 19.
