Katie Price's rumoured new boyfriend has been labelled an "absolute liar" by Imogen Thomas - who thought she was dating him.

The reality TV star - who split from her Argentinean lover Leandro Penna last week - was spotted with rugby player Danny Cipriani the morning after she enjoyed a visit to Thorpe Park theme park on Tuesday (04.10.11), angering glamour model Imogen Thomas who had hooked up with him during a trip to Las Vegas.

Imogen - who previously had an affair with Manchester United soccer star Ryan Giggs - wrote on her twitter page: "After everything in VEGAS & all the rubbish he told me about his issues, Danny Cipriani is the biggest bull****ter out there. Absolute liar. (sic)"

A friend of 23-year-old Danny said he was introduced to Imogen, 28, through boxer David Haye when the pair went to the US city to watch floyd mayweather fight Victor Ortiz in a Welterweight championship boxing bout.

The pair apparently spent a wild few days together, although Danny - who was previously in a long-term relationship with Kelly Brook - didn't consider the fling anything serious.

The pal told the Daily Star newspaper: "He's been seeing a few girls and enjoying life. Yeah, he's been with Imogen, but he thinks she's a drama queen. She'll grab any chance to date a well-known guy, especially a sportsman.

"It was just a bit of fun for Danny. He had no intention of dating her.

"He told me Kate's in a different league - lots of fun and full of passion, like he's never had before."
