Louis Tomlinson's girlfriend finds it difficult to deal with his fame.

The One Direction heartthrob is dating politics and sociology student Eleanor Calder and he admits it ''hasn't been easy'' for her to adjust to the amount of attention he receives as a member of the chart-topping 'Best Song Ever' boy band.

Louis told The Sun newspaper: ''It hasn't been easy at times. She gets pretty intimidated by it all. I mean, who wouldn't? She can't have Twitter or anything like that. At first, I was like, 'Just chill out a bit, it's fine', but now I understand where she's coming from. I can't expect her to deal with some of the stuff so easily. But with that said, I couldn't be happier with her.''

The 21-year-old star is often mobbed by his legions of adoring fans while trying to spend quality time with Eleanor and he was even spotted during a trip to Disneyland, despite wearing a disguise.

He recalled: ''Me and Eleanor went shopping a few times on the last tour. All was fine at first, we got out fine but went into Urban Outfitters and it just went berserk.

''We went to Disneyland. I wore glasses and a balaclava but it still didn't work. I wish there were one [that would work] but I still think it would be weird. I mean walking out in a f***ing proper disguise, like prosthetics. How seriously have you got to take yourself?''
