Mark Wahlberg and his model girlfriend—or is it fiancée now?— Rhea Durham took their family on a special Christmas outing to Santa's Grotto at the Grove Monday afternoon.

Decked out in a brown-leather jacket, red T-shirt and baggy jeans, Mark, 37, switched back and forth between carrying his daughter Ella Rae, 5, and son Michael, 3.

Mom Rhea, 30, was bundled up in a purple sweater and a long, tan scarf. She pushed 3-month-old baby Brendan along in a stroller.

Being the hectic crunch time before Christmas, the Boogie Nights stud and his brood were mingling among pressing mobs of shoppers. Take a camera's eye view of the retail action courtesy of Hollywood.TV:

Wahlberg will next be onscreen opposite lovely Rachel Weisz in director Peter Jackson's adaptation of Alice Sebold's bestselling novel The Lovely Bones.

Maybe Mark has that puzzled look because he's wondering if Academy Award-winner Weisz will be able to resist amusing cast and crew with her spot-on impersonation of Mark Wahlberg Talks to the Animals.
