Well according to Now, the rumours are now true and Justin has reportedly broken up with girlfriend Jessica Biel to get back with Cameron.

A source exclusively told Now: ‘Cameron and Justin have been back together for the past couple of weeks and he’s definitely ended things with Jessica.

‘For him, it’s a totally new beginning with Cameron. He really wants things to work this time around and he’s even talking about spending the rest of his life with her.’

Apparently Justin has even asked his mum, Lynn, for her approval – and she gave him it.

The friend says: ‘She wasn’t always a fan of Cameron, but she’s now told Justin he should ask her out before she heads off to Europe to start promoting Knight And Day with Tom Cruise.’
