BIEBERSI MAKE BEELINE FOR $320OM BREAKUP!

JUSTIN and Hailey Bieber’s jittery marriage has gone from yummy to life support and sources say she is setting her sights on snaring at least half of the aging teen idol’s massive $320 million fortune!

Insiders snitch the 27-year-old model has been hitting the Hollywood party circuit hard — with the 30-year-old Stay singer nowhere in sight — after a series of blowups over his exes, starting a family and his endless adolescent behavior.

Things were especially frosty between them on their recent trip to Las Vegas for the Super Bowl, where cameras locked onto a stone-faced Justin while Hailey bounced around with Khloé Kardashian during the halftime show to the music of his onetime rival Usher.

Sources snitch Hailey’s brazen display was humiliating for the fading pop punk — especially since Usher’s star is on the rise!
