One Direction's Liam Payne

 The One Direction star - who celebrated the end of his teenage years on Thursday - asked fans for donations to the Trekstock charity instead of giving him gifts in order to help young people with cancer.

Liam posted on Twitter: "Good morning everyone :) can't quite believe my life there's no bigger birthday present than what you've done for me in 3 years thank you xx

"If anyone was planning on buying me anything this is the 1st place u should go you could make difference to somebody (sic)"

The pop sensation celebrated his birthday last night with his new girlfriend Sophia Smith at exclusive nightspot Funky Buddah in Mayfair just over a week after he confirmed their romance.

Liam was all smiles as he arrived hand-in-hand with Sophia before leaving the club at around 1am, where the star snuck an intimate moment with his new flame before getting into a taxi.

His fellow One Direction group members - Harry Styles, Louis Tomlinson, Niall Horan and Zayn Malik - seemingly didn't make an appearance during Liam's celebratory night on the town, but the whole group had been spotted together filming their new music video in East London earlier that day.
