Louis Tomlinson is smitten with his new boo

Los Angeles - Louis Tomlinson is "smitten" with Tamara Bell.

The 23-year-old One Direction star - who split up with his long-term girlfriend Eleanor Calder three months ago - has been spotted getting cosy with the kinky model and fetish underwear designer at Glastonbury, and was spotted hand-in-hand with her as they walked through the backstage VIP area.

Speaking to The Sun newspaper, an onlooker said: "Louis was squeezing 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."

Tamara is old friends with Louis' bandmate Harry Styles and One Direction's hairdresser Lou Teasdale, and is the creative director of fetish lingerie brand Almeida, which was inspired by Fifty Shades of Grey.

Louis - who was joined by his bandmate Niall Horan at the Worthy Farm festival - was earlier spotted with Tamara at The Libertines' surprise gig on Friday night, and even put his hand on her bum at one point.

An onlooker previously said: "They were very flirty and clearly knew each other."

The Story Of My Life singers had to leave Glastonbury early to rejoin Harry and Liam Payne for One Direction's next tour date in Helsinki. 

Here is Louis's supposed new boo:
