Ashlee Simpson is one happy pregnant lady!

The expecting mom looked radiant as she took a stroll with her hubby Evan Ross and son Bronx Mowgli, whose father is Pete Wentz, in Toluca Lake, Calif. Bronx looks like he's having a blast with his step dad.

We have a feeling these two are going to be great parents to Baby Girl Ross!

For the outing, Ash wore a maxi dress, navy coat and ankle booties. Evan looked disheveled with a grey shirt, stained grey jeans and high top sneaks. Lil' Bronx wore a pizza-tastic t-shirt that we wish we had. We want pizza all day, every day!

The parents-to-be were married at the Diana Ross' home in Greenwich, Connecticut in August. Shortly after, Ashlee found out she was expecting on Thanksgiving Day.

The 30-year-old is due to welcome her first daughter in the summer.
