Robert Pattinson and Kristen Stewart are reportedly planning a voodoo 'wedding'.

The couple – who have refused to confirm they are dating since meeting on the set of the ‘Twilight Saga’ – allegedly want to show their commitment to each other at the unusual ceremony in December.

A source said: “Kristen is quite dark so she wants a ceremony performed by a New Orleans voodoo priestess.

“They’ve both had the crazy highs and lows you get when you’re intensely in love and thousands of miles apart, plus they’ve been coping with the immense pressure of conducting a relationship in the public eye.

“But they’ve now agreed they are serious and want to make a love pledge to show it.”

Kristen, 21, and 24-year-old Robert are keen to keep the details of the service secret and will not wear wedding rings after the service, instead opting to get each other special love tokens and matching tattoos.

The source explained to LOOK magazine: “Instead, Kristen and Robert want to buy each other tokens of devotion.

“They want to keep speculation to a minimum, so won’t get rings, but each is going to choose a present that reminds them of just how much they love each other.

“And they’re going to both get matching tattoos on their hips. They want tiny anchors to symbolise that they ground each other and keep each other calm when things get stormy.”
