Millie Mackintosh is to quit 'Made in Chelsea'.

The 23-year-old heiress will reportedly depart the E4 programme after marrying rapper Professor Green - whose real name is Stephen Manderson - in September, opting to join him on tour in the US instead.

A source said: "He is touring in America next year and Millie will join him as she didn't want to be apart from her husband so soon after tying the knot. She has told producers she's quitting the show and will join him there."

The couple will marry at upmarket Babington House in Somerset, South West England, and while Millie is close to her 'Made in Chelsea' castmates, they may not necessarily play a part in the wedding in the way they hoped because the groom - who has already insisted the nuptials won't feature on the show - doesn't want it to be a "circus".

The source added to the Daily Mirror newspaper: "Millie and her family are extremely well connected and decided Babington House would be the ideal wedding venue.

"The grounds are beautiful and hopefully the weather will be great. It's going to be a lavish yet intimate do. Millie's best chums, Rosie Fortescue, Cheska Hull and Binky Felstead, were all hoping to be bridesmaids but are yet to be given the nod.

"Stephen does not want his wedding to be a 'Made In Chelsea' circus."

One person not on the invite list is Millie's former boyfriend Spencer Matthews.

The source said: "Millie would rather gouge her eyes out with toothpicks than invite Spencer."
