The show, which will air on the Oxygen network beginning this spring, will reportedly see Mueller's custody battle with Sheen over their twin sons "feature[d] prominently".
During an appearance on The Ellen DeGeneres Show airing Friday, Hilton added that the truth behind the former couple's marital problems and the status of their current relationship will be revealed in the episodes.
"Let's just say there's a lot of drama in the show... It's really good," she said.
"There's a lot that happens."
Hilton, who lives next door to Sheen in Los Angeles, previously admitted that she believes Sheen and Mueller are "better as friends" than as a couple.
