HAS Kylie got a famous new boyfriend? Tongues are wagging in London after she was spotted on a secret date to the theatre with her recent co-star.

SINCE working together on the Doctor Who Christmas special, pop princess Kylie Minogue and actor David Tennant have struck up a warm rapport so warm, in fact, that tongues have started wagging in London.

The pair were spotted making a secret visit to the Old Vic to watch Cinderella just before Christmas and The London Daily Mail is reporting today they speak regularly on the phone.

"They kept the visit top secret and slipped in and out before anyone in the theatre had a chance to notice an A-list star and a famous actor were in the stalls," the Mail reported.

Tennant is currently dating 28-year-old Bethan Britton, who works for the BBC, while Kylie revealed in a recent interview that she has started dating again, though she wouldn't reveal any names.
