In our exclusive preview, Amanda (Hilary Duff) and David (Skylar Astin) are throwing a “Jack and Jill” party in lieu of having separate bachelor and bachelorette parties -- but the co-ed game night does not go over well with their friends.

“Hey babe,” Amanda says, pulling David close before she leaves. “You f**k a stripper, I kill you.”
