The Hangover star has been dating the Russian catwalk beauty since early 2015, but their relationship was called into question over the last few days as rumours of a break-up emerged.

Reports suggested the couple parted ways following a series of arguments over the holidays, but Bradley and Irina have now dismissed the gossip by heading out together in the Big Apple.

The stars were photographed walking hand-in-hand and smiling in Manhattan.

Irina has reportedly been apart from her actor boyfriend due to work commitments in Europe, as she was taking part in the recent Paris Fashion Week in France.

The brunette previously dated soccer star Cristiano Ronaldo, but they split in January, 2015, shortly before she struck up a relationship with Bradley in April (15).

Before getting close to Irina, Bradley dated another supermodel - British beauty Suki Waterhouse.

The actor was most recently seen on the big screen in Joy, a biopic based on the story of Miracle Mop inventor Joy Mangano, which reunited him with his regular collaborator Jennifer Lawrence.

The Oscar-winning actress recently revealed Bradley showed off his domestic skills by teaching her how to mop properly.

"You have to understand my mom was OCD (obsessive compulsive disorder) so I had to clean my room and do laundry and clean my dishes, but I don't think my mom would ever let a morsel of food get on the floor without bleaching the whole thing," Jennifer explained.

"Bradley's mom bought everything from (shopping network) QVC, and he had a Miracle Mop in his dorm room in college so he watched me mop in one scene and was like, 'Dude, no!" and showed me a better way."
