Prince Harry and Chelsy Davy split

Prince Harry and Chelsy Davy: It's off!

Prince Harry and Chelsy Davy have ended their relationship after five years together, according to reports.

The 23-year-old Zimbabwe-born Davy is said to have called time on her relationship with Harry just three weeks after their return from a holiday in Mauritius.

It is thought news of their split started circulating after Chelsy updated her status on Facebook to say she was no longer in a relationship.

A royal source told People magazine the split is amicable: 'They are remaining friends,' he said.

'There have been all sorts of reasons given [for the split] but suffice it to say they felt that it had run its course.'

According to the News of the World, post-graduate law student Chelsy – the daughter of a millionaire safari operator - had tired of the Prince's playboy antics.

But friends say the pair are both 'gutted' about the split and still love each other, but need to focus on their own lives.

A source told the Daily Mail: 'Harry knows he needs to knuckle down with his career with the military while Chelsy is taking her finals this year and wants to forge ahead with hers.

'They have rowed and split up before but this time it appears to be permanent.

'[But] Harry is still very protective of Chelsy and she is of him. They will remain friends.'

The couple met through mutual friends in 2004, and conducted a long-distance relationship for three years while Chelsy studied at a university in Cape Town and Harry enrolled at Sandhurst military academy.

Harry, who recently landed himself in hot water for uttering racist remarks on video, can now throw himself into his new two-year course with the Army Air Corps in helicopter pilot training.
