EXCLUSIVE PICS: Jennifer Garner Seen Smiling and Hugging Mystery Man While Out in L.A.

Ben Affleck's estranged wife was spotted happily hanging out with a handsome guy.

Jennifer Garner was spotted happily hanging out with a handsome mystery man in Los Angeles, California on Monday afternoon.

Ben Affleck's estranged wife
was friendly with the man as she laughed and hung out with him while seated in the passenger seat of a parked SUV near the Country Mart shops in Brentwood, the L.A. neighborhood where Garner lives.

During the animated 30-minute conversation, Garner -- who was casually dressed in a pair of skinny jeans, black T-shirt and flats -- hugged the man twice before hopping out of the vehicle. The 43-year-old actress did not appear to be wearing her wedding ring.

Affleck, 43, and Garner announced their plans to divorce in June, but have been spotted several times out and about together since their separation. The estranged couple have bought groceries, enjoyed a casual sushi dinner and most recently attended a funeral together in L.A. for a mutual friend.

In September, Garner and Affleck sparked reconciliation rumors when they were seen sharing a laugh outside a pediatrician's office in L.A. Just prior to that doctor's visit, the parents-of-three were also seen exiting a counseling center.

The source added that at the time of the breakup, they were believed to be working with a mediator on the terms of their divorce.

The A-list couple were married for 10 years, and have three children, Violet, Seraphina and Samuel.
