"American Sniper" actor Bradley Cooper and girlfriend Irina Shayk are acting like high school sweethearts as they were spotted out on a date night in London on Monday.

The Oscar-nominee even tried to hide from the paparazzi as he stepped into a taxi after leaving Novikov restaurant in Mayfair. The Russian Sports Illustrated model, however, could only giggle as she followed after him.

"It was the perfect shade to accentuate Irina's lithe frame as she curled up in the back of the taxi to conceal her identity next to Hollywood's most eligible bachelor," said Daily Mail.

"He was dressed down for the evening date, comfortable in the supermodel's company in a grey hoodie and a cap just tipped over his rugged, unshaven appearance."

Irina Shayk has split from long-time boyfriend Cristiano Ronaldo earlier this year, but the reason for their breakup was never explained.

The Russian model's rep sent a statement, "We can confirm Irina Shayk has ended her relationship to Cristiano Ronaldo of five years. Irina has been close with his family throughout the course of their relationship."

"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. Irina has no further comment at the time."

Bradley Cooper, meanwhile, split from girlfriend Suki Waterhouse weeks ago, but they remained friends and even hanged out during the Coachella 2015 last month.

Last week, Bradley Cooper and new girlfriend were spotted kissing last week and the photo caught everyone by surprise because there was no hint that they were dating.

A photo was published on Just Jared showing Bradley Cooper taking Irina Shayk's face in his hands while giving her a long kiss in New York City on May 3.

The 40-year-old actor and 29-year-old model looked like they were having an amazing time together - they held hands, cuddled, kissed, and laughed together after catching a performance of the off-Broadway play Hamilton," said the report.
