Katy Perryand Russell Brand have reportedly sent out wedding invites to their family and friends, with a guest list boasting of a hoard of celebrities from Rihanna to Jonathan Ross.
According to Taylor Swiftand David Walliams, are also rumoured to be on the guest list.
The couple are said to have also hired wedding planner to the stars, Glee actress Lea Michele and Eva Longoria, is also reportedly designing Perry's wedding gown.
A source told the tabloid: "It will be a mix of traditional Hollywood glamour with Katy's hair and dress, plus Indian touches like henna art on her hands and feet, an Indian tiara and hair brooches."
Meanwhile, guests will also be expected to attend the ceremony empty handed, after Brand announced that he and Katy do not want any wedding gifts, because they plan to donate whatever they receive to charity.
Russell explained: "Katy has got a good job and I've got a good job, it seems indulgent to ask for more things, so we're going to do something more worthwhile and humane with any money that people want to give us."
The funnyman has also defended his arrest for battery after 'lashing out' at a photographer, who tried to take snaps up Katy's skirt when they arrived at LAX airport last month.
He told interviewer Lorriane Kelly: "I tried to fulfil my masculine obligation to protect the woman that I love, but it is subject to legal enquiries - I've got to go to court - so I probably have to be careful about what I say in case I land myself into a complicated legal quagmire."
