Tulisa To Sing At Marvin And Rochelle's Wedding
And she'll be joined by Olly Murs and Pixie Lott at the showbiz nuptials...
The paper has also revealed more details about Rochelle and Marv's big day in July, including that there will be a strict dress code which will see men asked to wear black tie and women black cocktail dresses.
No kids will be allowed at the bash, the invites for which were printed in black and white with a diamonte centre.
The Sun also claims that Rochelle has lined up a deal with clothing firm Lipsy for herself and her bridesmaids to get matching pink and grey tracksuits to wear during their preparations.
And the couple are also claimed to have signed a six-figure deal with a glossy magazine for a spread on their nuptials.
They have, however, asked guests to make a donation to charity rather than buy them a gift.
Kelly Brook revealed last week that she watched Tulisa's sex tape "for research".
