"I'm alone in the bedroom, and you walk in," the actress, 39, says seductively. "You tell me don't speak. You'll take care of everything."

Applegate, who in real life has a 7-month old daughter, Sadie, plays Will Arnett's wife in Up All Night. The duo struggle to balance their working lives with raising a newborn.
