When you're a celebrity, you always have to assume there's a camera on you, even when you're just having a run-of-the-mill fight in the stands at Wimbledon.

This is a lesson Bradley Cooper and his girlfriend, supermodel Irina Shayk, learned the hard way on Sunday. The couple, who have been dating for more than a year, were spotted in the stands at the famed tennis tournament, and it looked like they weren't having the best time.

A bearded Cooper was seen speaking intensely to Shayk, who appears to be dabbing tears out of her eyes, before crossing her arms and refusing to look at him.

While there is no way to know for sure if the two really are fighting, or what they could be possibly fighting about, that didn't stop the Internet from speculating wildly the way the Internet loves to do.

However, as pointed out by a number of fans, there was a familiar face in the crowd that could have sown the seeds of discord between the two: Cooper's ex-girlfriend, Suki Waterhouse.

The 24-year-old English model dated the Hangover star for two years, from March 2013 to March 2015, one month before Cooper sparked a relationship with his current lady love.

Is Waterhouse's presence why the two were fighting? The world may never know (but online commenters seem pretty sure).

And to think, Cooper and Shayk were the cutest couple at the whole tournament when they were packing on the PDA in the stands just days ago. Check out the video below to see more.
