Bradley Cooper and Irina Shayk were reportedly spotted kissing in London, which has intensified talks about their rumored romantic relationship. Although the "American Sniper" was wearing a baseball cap pulled down over his face, reports indicated that they were seen kissing.

Cooper reportedly dropped off the Russian Sports Illustrated model at her hotel in London on Monday. People reported that Cooper was caught giving Shayk a romantic goodbye kiss before leaving the hotel premises. They were then spotted in the evening for a night out.

The duo have actually been romantically linked with each other since late April after they were caught getting cozy during a performance of "Finding Neverland" in New York City. This was also the same city they were seen holding hands and making out after watching "Hamilton" on Broadway.

"They walked around and, pretty much, any time they got to a spot where it was very dark, they started kissing and getting close," a source revealed. "They just looked like a new couple."

The rumored couple was also spotted cuddling at Rihanna's MET Gala after-party.

According to New York Post, they partied until 3 or 4 a.m. and even spent some time with their fellow celebrity friends, such as Tyler and Cameron Winklevoss, Leonardo DiCaprio, Gigi Hadid, Kendall Jenner, Adriana Lima and Kerry Washington.

Cooper and Shayk then moved to a private karaoke room, where they reportedly spent time making out all night.

"They were definitely together," a witness confirmed. "Bradley and Irina went down to the karaoke room super late together."

The actor reportedly broke up with 23-year-old Suki Waterhouse shortly before this year's Academy Awards. The two dated for two years. Shayk also went through her own breakup, ending her relationship with soccer superstar Cristiano Ronaldo, who she dated for five years.

Shayk's agent confirmed the split in a statement. Apparently, their split had absolutely nothing to do with claims that the model had some tension with Ronaldo's family.

"She has been close with his family throughout the course of their relationship," the agent said via Metro UK. "Any negative rumors with regards to Irina and the Ronaldo family are completely false and have not been a factor in the cause of the split."
