London: Emma Watson's former boyfriend Francis Boulle ended their relationship as he thought she was too famous.

The 'Harry Potter' actress briefly dated Boulle, who now stars in British reality TV show 'Made In Chelsea'. The actor said he called time on the romance because he didn't want to just be known as someone else's boyfriend. 

"We had a bit of a thing a while back but I have always been an ambitious person and I want to achieve my own notoriety for what I've done,' Boulle told Heat magazine.  'That's why I chose not to pursue it any longer, because I didn't want to be the boyfriend of some child actress," he added.
