Bossy in the boudoir!

In a promo for NBC's new sitcom Up All Night, Christina Applegate reveals her ultimate bedroom fantasy.

"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.

Watch Applegate explain her sultry -- and surprising! -- bedroom fantasy in the clip above. Check out the premiere of Up All Night September 14 on NBC.
