The 39-year-old former "Friends" actress was accompanied by co-star Owen Wilson, who complimented his leading lady by saying, "What can I say? You literally look great."

Meanwhile, John Mayer was busy chatting it up with press, explaining that he prepared himself to be asked about Jen's sexy nude GQ cover pose.

"I sort of told myself in the car that I was going to talk about dogs and movies and fonts," the "Why Georgia?" singer says. "On the GQ cover, fonts only."

Also in attendance were Hollywood stars including Jen's BFF Courtney Cox, along with "Grey's Anatomy" beauty Katherine Heigl.
