Sam Faiers' grandmother looks set to appear in 'The Only Way Is Essex' Marbella special.

The reality star is heading out to the sun-soaked Spanish holiday destination for a summer episode of the ITV2 show, and is "begging" series bosses to include her "mad" tracksuit-wearing Nanny Wendy - who lives in Marbella - in the programme.

She said: "We are begging for a series in Marbella and I have told them that if they go they are getting Nanny Wendy in it.

"She is mad, wears Juicy tracksuits, has a little shih tzu and drives around Marbella in a convertible."

However, the 'TOWIE' summer special could be forced to go up against a rival show, 'Marbella Beach', developed by former 'Big Brother' winner Brian Belo, who claims to have come up with the idea for the ITV2 series in the first place.

An insider recently said: "'Marbella Beach' will score where other reality shows fail. It will have sun, sea and lots of sexy action with bikini babes and hunks in trunks."
