Beyoncé Flashes Cleavage in Racer Outfit at F1 Las Vegas Grand Prix

Beyoncé got hearts racing at the F1 event in Las Vegas … bringing more excitement to an already electrifying event when she bared her cleavage.

The singer-songwriter led the celebrity attendees at Saturday night’s race … walking into the event on the arm of her man, Jay-Z — though we doubt anyone looked much at him.

After all, his wife wore an alluring white and black leather top — much in the fashion of a racecar driver’s uniform … though she pulled the zipper of hers down to the middle of her chest, leaving little to the imagination.

Queen Bey and Jay have taken some time off of their busy schedules to simply enjoy each other’s company recently … even sneaking in to Kris Jenner‘s 70th birthday party, sources told us earlier this month.

Just like KJ’s bday, this is another star-studded event … with Ben Affleck, Machine Gun Kelly, Michael Douglas, Catherine Zeta-Jones, Nina Dobrev, Gordon Ramsay, Magic Johnson and many more A-listers in attendance.
