Rihanna ‘to perform at Brangelina’s party’

Rihanna is set to perform at Brad Pitt and Angelina Jolie's Olympic Games party.

The Hollywood superstars are currently living in London while Angelina shoots her latest movie Maleficent. They have embraced the English lifestyle with gusto and are planning a huge bash to celebrate the start of the London 2012 Olympic Games later this month.

The engaged couple are apparently pulling out all the stops for their UK-themed party.

"They've been having renovation work done, including installing giant black chandeliers and covering the walls in black chiffon drapes," a source told UK magazine Grazia.

"There will also be British themed canapés like fish and chips and beef Wellington. Rihanna may even make a guest performance, after she wowed at Brad's Make It Right foundation gala in March."

The evening will start with a charity dinner in the city, after which guests will be transported to Brad and Angelina's home to continue the fun.

Among those rumoured to be taking part are David and Victoria Beckham, Nicole Kidman and Britain's Prince Harry, Prince William and the Duchess of Cambridge.

In all, it's rumoured the party will cost £60,000. It is being held on July 25, two days before the official opening ceremony.
