So for the latest issue of Marie Claire, the actress looks totally cool, natch, going pantsless in a pair of Gucci briefs and a tuxedo coat, flashing that adorable grin.
Inside she gets up close and personal with Jason Bateman, nuzzling her costar in that same getup as the two promote their comedy Horrible Bosses...
Speaking of work, the actress reveals the trials of her early years in the biz.
"I spent my first paycheck on a vintage Mercedes. I was struggling a little in New York, working as a waitress at Jackson Hole but not really getting any consistent acting work," Jen says. "Then I moved out here to Los Angeles, and I started getting pilots and working pretty regularly. I still didn't make any decent money until I got on Friends."
If she hadn't followed in her dad John Aniston's footsteps, though, Jen reveals she might've become an interior designer.
"I love seeing a house and thinking about how it should be redone or restored," the Friend says. "I spent a lot of time doing my current house, and it's beautiful. It's like a beautiful work of art, and I'm very proud of it."
