So sweet! Model Rhea Durham, 31, plays with her youngest child, son Brendan Joseph, outside of Barneys New York on Thursday.

The family is currently in the Big Apple while husband Mark Wahlberg films his latest movie, The Other Guys.

In addition to 13-month-old Brendan, Mark and Rhea are also parents to Michael, 3 ½, and Ella Rae, 6, as well as a baby on the way — reportedly a girl!
