Alison Sweeney on Hollywood Moms Night: "Nothing's Off Limits"

Have you ever wondered what some of Hollywood's famous females talk about when they get together? TVGuide Network is now giving viewers a peek with the upcoming special Hollywood Moms Night(Sunday at 8).

"There are things that all women have in common when they get together with their girlfriends and this is a fun opportunity to share that and show a different side of us to our fans," Alison Sweeney says. Sweeney, who stars on Days of Our Lives and hosts The Biggest Loser,  and her best friend Ali Landry invite Denise Richards, Niecy Nash and La La Anthony for one of their famous dinner parties and it doesn't take long before the conversation heads south — literally. (Watch the clip below.)

"Nothing is off limits," Sweeney says. "There were certain topics I was extremely uncomfortable with, but if Niecy wants to talk about it, I'm OK with it -- I can hang. It's more fun to let people go where they want to go and if there's a boundary they feel comfortable with, that's OK too." Speaking of the Dancing With the Stars and Reno 911 alum, Sweeney says Nash will be the celeb that surprises viewers the most. "Even people who know and love Niecy know that ... she will surprise or shock you every time she opens her mouth."

Hollywood Moms Night airs Sunday at 8/7c on TV Guide Network.
