Could “The X Factor” Torpedo Britney Spears’ Engagement?

Will The X Factor mean the ex-factor for Britney Spears and fiance Jason Trawick?

The show’s demanding schedule is causing a massive rift in the couple’s relationship, snoops tell RadarOnline. At the root of the issue: Jason — who is also Britney’s co-conservator and manager — is upset that he’s gone from big-time Hollywood agent to stay-at-home dad.

“[Jason] feels like he is the house husband and errand boy in the relationship and that isn’t what he signed up for. Part of his role as co-conservator is to be with Britney every second that she is on the set of The X Factor and he is getting fed up with it.”

Jason and Britney announced their engagement in January. The dazzling diamond engagement ring was designed by celebrity jeweler Neil Lane. Lane created the tiara-motif sparkler with a round, perfect white diamond in a handmade platinum setting that “looks like a mini crown.”

Brit’s judging gig is earning her a hefty $15 million paycheck, but the pop tart will have to question whether the cash comes at a cost to her love life, says one squeal.

“Their relationship has been majorly rocky ever since she started filming The X Factor. They are constantly fighting about everything and it isn’t good.”

Britney’s come under fire for her harsh judgment of contestants on the reality show, with one news source coining the moniker “Bitchy Spears” to describe her erratic behavior. Jason is reportedly sick and tired of dealing with his famous girlfriend’s on-set antics.

“The mixing of business with pleasure has really damaged their relationship, and they are both really unhappy at this point.”
