The pair appeared in good spirits as they were pictured giggling close to each other in the street.

Imogen donned a black mini dress and shielded her shoulders with a sophisticated black blazer, teaming it with a Jacquemus handbag.

She styled her ensemble with opaque fishnet tights with lace detailing and knee-high leather boots.

Her mystery man wore a white padded jacket and jeans, paired with white sneakers.

MailOnline has contacted Imogen’s representatives for comment.

Imogen recently admitted she owes her Big Brother stint to her lavish lifestyle with a £10million property empire and affairs with footballers.

She entered the house alongside the late Nikki Grahame and Pete Bennett, as a then 23-year-old waitress.

In a new interview ahead of the reality series’ reboot last month, Imogen revealed she is ‘technically’ no longer working.

Leaving the show on day 86, the former Miss Wales was inundated with offers for photoshoots and interviews after being named ‘Wales Sexiest Woman’.

Imogen famously dated Jermain Defoe and had an affair with then-married footballer Ryan Giggs, who imposed a gag order on her.

She remembered her “overnight fame” after leaving the house, she said The sun: ‘I came off the show and started working from day one. It was great, I made a lot of money.

“It was just all a bit surreal because I went in as a hostess and came out just wanting to make money and be wanted by everyone.”

Imogen revealed she now owns two houses in Wales, a flat in Notting Hill and two townhouses in Chelsea, one of which she lives in.

“Because I own property, I have a lot of passive income, so technically I don’t work,” she explained.

In 2011, Imogen’s affair with then-married footballer Ryan came to light after he was mentioned in the House of Commons.

Giggs had waged a desperate campaign to keep his name secret, not only issuing a court order but also threatening to sue Twitter users for leaking his name.

Ryan settled his £40million divorce from wife Stacey in 2017 after it emerged he was also having an affair with his brother Rhodri’s wife, Natasha Lever.
