"Name three things Matthew Broderick does when he sleeps," game host tWitch of So You Think You Can Dance fame asked Parker of her husband.
"Not snore, smiles, and reaches out for me," she said within five seconds as per the game's rules.
Cyrus who was filling in for Ellen DeGeneres who was out sick, was then asked to "name three things you can't resist," to which the pop star responded, "My cellphone, cute boys and girls and...candy!"
In the final round, Parker was unable to contain her laughter when Cyrus held nothing back when describing three things she has hidden around the house.
"Pot, alcohol and cats. Lots and lots of cats, more cats than alcohol, I promise," she replied.
Cyrus recently made headlines for revealing that she's not a fan of Mariah Carey. "I've never really been a fan, because it's so much about Mariah Carey. That's part of her shtick; I can see through that," she says in the October issue of Elle.
