There won't be any more power couples left in Hollywood if this happens!

Gisele Bundchen and Tom Brady's marriage is reportedly on the rocks, and insiders think it won't be too long before the model and quarterback call it quits, OK! magazine reports.

Atlhough the Victoria's Secret stunner publicly gushed about her hubby in an Instagram post for his birthday on August 3rd, all is not what it seems behind the scenes. "Gisele is ramping up the social media activity because her marriage is breaking down,” a source dished to the mag. "Things between Tom and Gisele have been strained for a long time," the source added, noting that the pair have been "plagued by the same problems” for years. We wonder what those problems are?!

The tensions came to a head at the football star's birthday dinner earlier this month. “Tom and Gisele had a massive fight, and she stormed out. [They] each dredged up every issue with the other that they’d been suppressing," the insider revealed.

At stake if they pull the plug? An estimated $460 million and their three children! The cat walker is already making it clear that Tommy Boy better work to get back in her good graces, or she's headed to her homeland without him! Something that didn't help their state of affairs? The Patriot QB being on the same private jet to Vegas as Ben Affleck and his fling Christine Ouzounian, who snapped a selfie wearing the athlete's Superbowl rings.

“Things have never been this bad. Gisele told Tom that if he didn’t make more of an effort, she might go back to Brazil for a few months to think about the future," the source continued. That sounds like a threat!

First Ben and Jen, then Gwen and Gavin, and now this!
