She's long claimed to have enjoyed a saucy fling with Russell Brand after they met on Celebrity Big Brother's Bit On The Side - and reality star Lauren Harries now believes he just used her for sex.

While the funnyman denies there has ever been any such affair, transgender Lauren, who was once known as James, tells Star magazine their tryst lasted for six months in 2006.

The antiques expert told the publication that her new single, All Dressed Up, is inspired by the comedian and the feelings of rejection he left her with.

Not happy: Lauren Harries has claimed that Russell Brand 'used her for sex' after they met on Celebrity Big Brother's Bit On The Side in 2006 - although he denies they were ever romantically involved

Making her mark: The transgender star, once known as James is releasing a new single, All Dressed Up which she says was 'inspired by Russell Brand'

'It's about being dressed up to go out, then being stood up by a man, feeling sh***y and crying about it. Russell Brand inspired me to write it.

'He left me all dressed up with nowhere to go. I don't think Russell wanted to be seen with me, so we didn't go out. We had our moments, but he can't admit to it.

'It was going on for six months at least. Let's just say he liked the bedroom department, but that was all! That was all I was good for.'

Quirky look: Meanwhile, Brand was last pictured on Monday arriving at the Proud Archivist, a series of readings, musings and other discussions of the unexpected

Denial: Russell said of Lauren's claims back in 2013: 'Lauren's claims are as fraudulent as her evaluation of Ming vases on Wogan. And before she starts, I also have not had sex with a Ming vase or Wogan'

Russell vehemently denied anything sexual with Lauren, who is set to front a new dating show, took place telling the MailOnline in 2013:

'Lauren's claims are as fraudulent as her evaluation of Ming vases on Wogan. And before she starts, I also have not had sex with a Ming vase or Wogan.'

Brand is referring to Lauren's past as James Charles Harries, who appeared as ten-year-old child antiques expert on Terry Wogan's chat show in 1988.

Meanwhile, Brand was last pictured on Monday arriving at the Proud Archivist, a series of readings, musings and other discussions of the unexpected.

Swathed in a couple of scarves and wearing trousers and trainers, Russell, who was once married to Katy Perry and dated Jemima Khan, wore his long locks in a top knot.
