Meet the new Ms. Reese Witherspoon

Two months after admitting it was bizarre seeing ex-wife Reese Witherspoon with Jake Gyllenhaal, Ryan Phillippe is quietly moving things forward in his own love life.

After months of speculation about their relationship, he proudly accompanied his Stop-Loss costar Abbie Cornish to the 2008 Australian in Film Breakthrough Awards – their first major event as a couple.

“They were adorable,” says a guest. “He had his arm around her and they were cozy and comfortable.”

When Cornish – who was being honored with a Breakthrough Award – was introduced, Phillippe rubbed her back while she leaned against his shoulder. Throughout the evening, they held hands.
