She pulled the plug on her TOWIE career five years ago and has since found love with footballer Andy Carroll. 

But Billi Mucklow will make a brief return to the show that found her fame on Sunday night as she swoops in to offer relationship advice to her brother, and ITVBe's newest recruit, Sam.

Viewers recently watched the newcomer ask Shelby Tribble out on a date following her split from Pete Wicks, and now his older sister will do all she can to help her younger sibling get the girl.

It's claimed Billi will make a number of guest appearances throughout the series, something that will no doubt be welcomed by long-time viewers. 

The blonde made her debut when the hit series was still in its infancy with only three seasons back in 2011. She made the decision to quit the cameras two years later with Kirk and Mick Norcross, Debbie Douglas and Danni Park-Dempsey. 

Viewers will remember the star's failed relationship with Tom Kilbey, the brother of her best friends Cara, who later enjoyed a tryst with Lydia Bright.  

After leaving the series Billi began dating Premier League footballer Andy, with the pair later welcoming two children; Arlo, three, and Wolf, eleven months. The West Ham star also popped the question during a romantic trip to Rome. 

But Billi - who owns fitness studios Bikram Yoga Essex, Inferno HIIT and Cycle Rhythm - will now make her return to TV after Sam enlists her help to woo Shelby. 

Sitting down with his sister in a new teaser, Sam tells her: 'I need some sisterly advice.' 

A prying Billi then asked: 'Have you got your eye on anyone?' prompting Sam to admit: 'I had a good time with Shelby. She’s gorgeous.'

The teaser went on to show Sam and Shelby flirting at a bar, with Sam cheekily asking: 'Am I daddy material?'

But instead of going behind Pete's back, Sam decides to do the respectable thing and talks to Pete about his feelings for her, admitting they have enjoyed a string of dates off camera. 

'Look, I wanted to talk to you. Me and Shelby have been seeing each other…' he affirms, but Pete - who split from Shelby after she discovered he'd been sending racy messages to other girls - doesn't look pleased.
