Lauren Goodger, Mark Wright split over cheat claims?

The Only Way Is Essex star Lauren Goodger has been photographed without her engagement ring, sparking rumours of a split with fiancé Mark Wright.

The 24-year-old's hand was seen unadorned while she partied in London last night, following claims that Wright had cheated with ex-lover Lucy Mecklenburgh during a trip to Marbella.

Goodger "stormed out' of their flat on Tuesday after Mecklenburgh went public with their alleged affair, according to The Sun.

"We kissed twice," Mecklenburgh told New Magazine. "The first time was in Pangea, and then we kissed when we were on our way back to the apartment complex, where we were all staying... There was a drunken kiss. But out of respect for Lauren, that's all I'll say."

A spokesperson confirmed to the Daily Mail that the girls were scheduled to have a "showdown" over the claims and the impact they have had on Goodger and Wright's relationship.

"[The showdown] was meant to happen last night but Lauren had her promotional stint for her tanning products and Lipsy so they're speaking now instead," they explained.

Goodger earlier travelled to Lakeside shopping centre to promote her new line of tanning products, but was accompanied by her Only Way Is Essex co-star James 'Arg' Argent instead of Wright.

The spokesman said of the nightclub owner's absence: "Lauren went out last night to celebrate the success of Lauren's Way tanning products and Mark had a personal appearance in Hornchurch so he couldn't go to Embassy."

Wright previously denied suggestions that he had cheated on Goodger in Marbella, tweeting that a series of compromising pictures were "not one bit what they look like".
