Although the former couple - who split up four months ago after two years together - enjoyed an intimate dinner at 'The Little Door' restaurant in Los Angeles earlier this week, those close to them insist they have decided to just remain friends as they are too busy with their careers to commit to anything serious.
A source told RadarOnline: ''Jennifer and Nicholas are not back together, their dinner date was innocent.
''They are still very close friends, despite their break up, and regularly text or phone each other from across the pond. With Nicholas being in Los Angeles for business meetings, it gave them the chance to get together and catch up on what's going on.
''Both of them are so busy with work right now that they just don't have time to commit to a relationship. But they still want to remain close friends, simply because they just love each other's company so much.''
However, Jennifer, 22 and Nicholas, 23, haven't ruled out a reconciliation in the future.
The insider added: ''They're not ruling out getting back together in the future, but for the moment they are just very close friends.''
