In the show's Sept. 22 season-two premiere, Aniston, 41, will play a "shrink named Bonnie" to Cox's character Jules, the show's executive producer Bill Lawrence told Entertainment Weekly.

"Kind of a get-too-involved-in-her-life-type of therapist," Lawrence added.

Aniston also made a new friend on the set: actor Josh Hopkins, who plays Cox's love interest on the show. As reported in the new Us Weekly, Aniston and hunky Hopkins, 40, had a romantic Sept. 2 date at West Hollywood's Madeo eatery. "They seemed to enjoy each other's company," a fellow diner tells Us.

It's the second post-Friends reunion for Aniston and Cox; in 2007, they shared a passionate kiss on Dirt, Cox's short-lived FX drama.

Will Aniston return to Cougar Town? "I'm crossing my fingers that if she has a good time it'll happen again," Lawrence said.
