Angie Harmon and Jason Sehorn's soon-to-be-born child should gear up for a wild ride.
"Our two girls are very excited," Sehorn, 37, told PEOPLE in Las Vegas Saturday at the opening of LAVO. "If it's a boy, they'll drag him around and dress him in girl's clothes. If it's a girl, God bless her, our other girls will beat her down out of love."
Luckily, Harmon, 36, who is due this winter, is getting some experience refereeing tussles, playing a homicide inspector on the ABC drama Women's Murder Club
. Sehorn, a former NFL defensive back, should also be equipped to handle any skirmishes.
As for the world their child will come into, Harmon said, "Our house sounds like a Justin Timberlake
concert. From the time they get up to the moment they go to bed there is screaming and squealing. Our girls have no idea what an 'inside voice' is."
Still, the couple experienced so much happiness when Finley Faith, 4, and Avery Grace, 3, were babies that they said they are actually excited about more diaper duty and sleepless nights.
