London: British pop star Robbie Williams is nursing a broken heart after his girlfriend, Norwegian actress Natassia Scarlet Malthe, dumped him earlier this month.

The couple has been dating since last year but Malthe allegedly put an end to the relationship because of her hectic work schedule.

Contactmusic.com quoted a close pal of Malthe as saying: "Robbie and Malthe had a frenzied romance and really loved each other. But the relationship was almost too intense. Robbie's hardly doing any work at the moment while she is a star on the rise. She didn't have time for him."
