Harry Styles is practising yoga.

The One Direction star has reportedly taken up the soothing exercise to help control his stress levels after bandmate Zayn Malik quit their 'On the Road Again' tour and returned to England amid rumours he had cheated on his fiancée Perrie Edwards.

The 21-year-old star is said to have been practising yoga and meditation in an attempt to rid himself of worries since Zayn was forced to deny the allegations in the same week that member Louis Tomlinson split from his long-term girlfriend Eleanor Calder.

A source said: ''When Harry was in Bangkok he travelled for 40 minutes on his own to see one temple and embrace his spiritual side.

''He's been meditating and doing yoga in Thailand and also spent time wandering around markets to soak up the culture.''

Rumours of Zayn's alleged infidelity followed the release of a photograph which appeared to show him holding hands with a blonde backpacker named Lauren Richardson as the band partied in Thailand.

While Louis - who split from Eleanor two weeks ago - was also photographed in a cinch with an unknown girl in a pool at the same party it is believed Harry has been more interested in soaking up the country's culture.

A source told The Sun newspaper: ''Harry likes to party but he thinks it's important to have some balance.

''It can be seriously stressful being on the road all the time so it's good for him to explore the countries.''
