MUMBAI: Singer Harry Styles and his girlfriend Nadine Leopold are getting too much serious with each other and have reportedly inked matching tattoos.

According to a source, the 21-year-old One Direction member arranged for an artist from his favourite tattoo parlour, Shamrock Social, to visit his home in Los Angeles so he could prove his commitment to the model, reports femalefirst.co.uk.

“Harry is having to do a lot of the running with Nadine,” Heat magazine quoted the source as saying.

“He knows what his reputation as a womaniser is like. He's desperately trying to show her he's serious about her and she's not just another girl,” the source added.

The duo, who have been dating each other since November last year, are said to have got one another's initials etched onto their bodies, but it is unclear where.
