"[Estela is] really excited," Landry told of her daughter's thoughts on her pregnancy. "She knows there's a baby coming and that she's going to be my little helper. We'll wait and see because she's used to having all the attention and now she's going to have to share it."

During her second pregnancy, the former Miss USA winner and one-time Doritos spokeswoman, 38, had plenty of fellow celebrity moms to lean on. Every month, she trades parenting tips over a potluck dinner with moms including Alison Sweeney, Denise Richards, and Candace Cameron Bure.

Their gatherings are being taped for a new TV Guide Network series set to air this November.
