Nicholas Hoult wants to rekindle his relationship with Jennifer Lawrence.

The 25-year-old actor, who split from the Oscar winner last August after three years of dating, is reportedly ''determined to win her back'' even though she has moved on with Coldplay frontman Chris Martin, 38.

A source close to the British star claims he is vying for her attention on the set of 'X-Men: Apocalypse' in Canada.

The insider said: ''He's hoping that during filming, he'll win her heart again.''

But the blonde beauty, 24, only has eyes for Chris and he regularly visits her on the set.

The insider added to America's Star magazine: ''She's really into Chris.''

The former couple first started dating after meeting on the set of the first 'X-Men' film in 2010.

Nicholas was most recently linked to former 'Glee' star Dianna Agron and was spotted showing her round his favourite UK haunts in April.

A source previously said: ''Nicholas is very low key so at first Dianna would just tag along with him to the pub and she'd be part of the gang.

''No one thought much about it but recently they've become a very close and are behaving quite couply.

''Dianna doesn't look it, but she's really down to earth and loves how Nicholas lives a normal life.

''They've been friends for a long time. It's early days but things between them are ticking along nicely.''
