"Million Dollar Listing Los Angeles" star Josh Altman is going to be a dad of two.
"We're expecting baby number two!" Heather told Extra.
"We're super excited," Altman said.
Altman and Heather are already parents to 21-month-old daughter Alexis Kerry.
"[We won't] be so crazy about everything," Heather said. "The rules will be a little more flexible this time."
"Our world is going to revolve around them," Altman added.
Heather shared a photo Thursday on Instagram of Alexis wearing a pair of fairy wings and a hat with pom pom ears.
"Thursday motivation - wear your personality," she captioned the post.
Altman stars on the Bravo series "Million Dollar Listing Los Angeles," which follows Altman and other real estate agents as they sell high-end properties in the Los Angeles area.
The show returned for an 11th season last week.
