He is enjoying a well-deserved rest during the Christmas holidays.

And Harry Styles showed off his unlikely new hobby as he took an ice-cold dip in the River Thames with his girlfriend Taylor Russell.

In the snap shared by a fan on Instagram, the 29-year-old singer showed off his ripped physique as he emerged from the water after the refreshing dip.

Taylor donned a black unitard and matching wool hat as she walked down the dock with her boyfriend.

Harry and Taylor first became romantically involved after being spotted on an art gallery date in London in June.

Since then, the pair have been spotted on several outings as they take their romance to new heights.

The Watermelon Sugar singer reportedly sees 'a future' and is 'in love with Taylor', a source revealed We weekly last month before noting that he “likes to spend as much time with her as he can.”

The insider claimed: 'Things are very serious and Harry definitely sees a future with Taylor.'

The insider also said that the One Direction vet accompanied Taylor to an after-party for the final night of her play, The Effect, at the National Theatre.

“Even though they are both busy with their careers, they support each other every chance they get,” the source told the outlet.

Harry recently debuted his new buzz cut after sending fans into a frenzy with his surprising new look while enjoying a U2 concert with Taylor.

He caused a social media frenzy when it was revealed he had shaved off his iconic curls, even prompting one person to label his behavior as 'unhinged'.

Harry has reportedly been staying in a swanky £2,500-a-night hotel in central London as construction work continues on his £50million mansion.

He is said to be living out of a suitcase in the very lavish accommodation, with Taylor keeping him company.

Harry spent £13 million on neighboring 18th-century houses in north London in 2020, which he knocked into one property before setting about transforming them.

A source said The sun: 'Harry has understandably kept a good distance from his pad while the major works were underway, checking into a lavish hotel while in London. His girlfriend Taylor is staying with him.'

'They keep a low profile, go for coffee and snacks and cycle through London like tourists.'
