FREDDIE PRINZE JR. CANCELS MR. MOM DUTY — & SARAH MICHELLE’S NOT HAPPY!

SARAH MICHELLE GELLAR is furious at husband FREDDIE PRINZE JR. for giving up his real-life role as Mr. Mom.

The "Ringer" star and the former "24" actor have been arguing because Freddie broke their "baby pact" that he would be a stay-at-home dad and raise their daughter Charlotte, now 2, while Sarah focused on her career.

"Sarah wasn't happy when Freddie started auditioning again, and she was livid that he got a starring role on a new series," a close source told The ENQUIRER.

"Sarah stayed home for the first year and a half, but since Freddie wasn't booking any solid acting gigs after '24,' she took the role in 'Ringer.' Now she's bent out of shape because their plan was always to have one non-working parent raising their daughter. "While Freddie loves his daughter, he's just sick and tired of 24/7 baby duty."

Sarah, 34, and Freddie, 36, met on the set of the 1997 horror film "I Know What You Did Last Summer" and got hitched five years later. In an upcoming untitled NBC sitcom, Freddie plays a nerd who dumps his fiancee, portrayed by "7th Heaven" actress Sarah Wright.

While doting dad Freddie is happy about hanging up his apron, Sarah is frantically interviewing for extra nannies and trying to juggle their different schedules, say insiders.

"Sarah and Freddie are fighting, especially when he tells her to relax and that everything will work out," disclosed the source.

"He feels Sarah is acting like a bigger baby than Charlotte."
