The 21-year-old, who had a handbag with ‘Peace’ and ‘Love’ written on it, looked shaken in the back of a taxi after model boyfriend Oliver Cheshire got embroiled in the argy bargy outside Sketch in central London.
A source told The Daily Star: ‘One bloke got thrown up against a shop window and knocked unconscious.
‘Pixie was really upset and was crying and arguing with Oliver as they left in a cab.’
Pixie said recently that she had no plans to move in with Oliver because she didn’t want to lose the ‘magic’.
Asked by Look magazine if he was The One, she replied: ‘I don’t know, we’re so young. We’ve been together for a year and a half, which isn’t that long in the grand scheme of things, but it is for me. It’s the longest I’ve ever been with someone.’
