Chantelle Houghton and Rav Wilding have called time on their relationship.

The 'Celebrity Big Brother' star and the 'Crimewatch' presenter - who started dating at the end of last year - have decided to end their romance following a public argument in London's Richmond Park over the weekend, which left Chantelle in floods of tears.

Writing on twitter, Rav said: "Wanted to clarify situation after speculation 2day. Sadly Chantelle & I are no longer in a relationship as I've had to draw a line under it.

"It's been a really difficult week and a lot has gone on, & I appreciate everyone's kind words. The relationship wasn't what I wanted so badly and wasn't the genuine thing I thought it was.

"It's so upsetting as I genuinely & truly loved Chantelle, but the publicity side isn't always reflective of the truth. All I ask is that you don't believe everything that's written, and thanks again to everyone who's been in touch - means a lot x (sic)"

Although the couple - who had enjoyed a champagne picnic prior to their explosive row - had previously gushed about each other, Chantelle recently admitted they were experiencing some problems as he couldn't accept her past.

Chantelle - who was formerly married to singer and fellow 'Celebrity Big Brother' star Preston - said: "It doesn't anger me but I don't like someone wanting to change my past because I wouldn't change it for anything - I don't regret any of it.

"I don't think Rav wants to acknowledge it, but what went on between me and Preston is important."
