It was common knowledge that Bradley Cooper and Irina Shayk were dating, but the couple for long refused to make their relationship official. However, when the two were at the L'Oreal Red Obsession Party in Paris on 8 March, they posed for photographs together and were even spotted kissing.

The next day, the 41-year-old actor and his 30-year-old model girlfriend attended the Arop Charity Gala at the Opera Garnier. Cooper and Shayk reportedly started dating back in May 2015, but had kept things under wraps, despite being spotted together on various occasions.

Last week, rumours surfaced that the two had split after the actor was spotted in West Hollywood with Naomi Campbell. Cooper put the story to rest when he attended the Givenchy show at the Paris Fashion Week in which Shayk walked the runway. According to sources, the Hangover actor could not take his eyes off his girlfriend as she walked the ramp.

Shayk most recently featured in the 2016 swimsuit issue of Sports Illustrated for the 10th time. In an interview with ET she recalled how dangerous it was to pose on the beach in Tahiti which was swarming with sharks and sting rays. "It was kind of dangerous because a shark could literally bite my booty and the swimsuit off," she recalled.

And as for being one of the older women in the issue that featured mostly models in their 20s, she said, "They discovered me back in 2007. I'm still here, and I'm not going anywhere."

Cooper previously dated English model Suki Waterhouse, while Shayk was in a relationship with Cristiano Ronald for five years.
