The singer was spotted at the event in Somerset, England holding hands with the brunette beauty, and sources say the star looked "smitten" with Bell.

Tomlinson was also joined at the festival by his bandmate Niall Horan and friends from his U.K. hometown of Doncaster.

A source tells Britain The Sun on Sunday newspaper, "Louis was stroking the back of her neck and squeezed her bum before kissing her affectionately. He looked smitten and they appeared to be very familiar and cosy with one another. He was glued to her side, even though he had a few of his Doncaster mates with him."
