Expectant mama Camila Alves leads the way as she and son Levi, 16 months, stroll in Malibu, Calif. on Monday.

Although Camila is looking casual here, the model has been spotted out and about at events in the past week — on Friday, she hit all the right notes in a black one-shouldered gown and was pretty in purple last Tuesday!

She and Matthew McConaughey expect their second child in late December/early January.
