Rumor has it Maya Rudolph is pregnant.

According to The Hollywood Reporter, the "Up All Night" star, 40, has informed NBC that she is expecting her fourth child with husband Paul Thomas Anderson. The couple already has three young kids Pearl, 7, Lucille, 3, and Jack, only 19 months.

Sources also tell THR that Rudolph's pregnancy is expected to be written into the revised version of the show, now that Christina Applegate has announced her departure. Still, "Up All Night" might not return to the small screen at all, considering the series' writers are allegedly looking for new jobs.

Well despite the show's reported reboot, busy mom Rudolph is set to be up all night. (If she's pregnant, that is!)
