Rihanna will be ringing in the holiday season in London.

The singer will be turning on the Christmas lights at London's Westfield Stratford City shopping center Monday evening.  According to the Daily Mail, she will received £5 million for the gig.

Organizers expect 20,000 spectators the event where Rihanna will also perform. The artist’s latest album, "Unapologetic," was released on Nov. 19.

A source told the Sun newspaper that Rihanna is looking forward to turning on the Westfield Stratford Christmas lights, an honor that was carried out by Justin Bieber last year. Rihanna incidentally turned on the lights at Westfield Shepherd's Bush in 2010.

“Rihanna’s thrilled she has been asked again. She knows it’s a big deal and is totally up for it. Westfield has had a great year due to the Olympics and want to fork out to celebrate,” the source said.

“Even though the final contract is still being thrashed out, they’re prepared to pay up to £5million for her.”

Myf Ryan, general marketing manager for the shopping centre notes how much of a huge event the lighting is for Westfield Stratford City.

“The Christmas light switch-on at Westfield Stratford City is one of the highlights of the festive calendar,” he said.

“This year we want to thank our loyal shoppers by giving them something they’ll never forget.”

Rihanna was reportedly a UK favorite all year. While the Spice Girls performed at the 2012 Olympics in London, the singer was among the top suggestions to perform during the games.

Rihanna will turn on the lights with the help of ambassadors from Westfield's charity partner, Save The Children, according to the Mail. After performing, she will do a meet and greet with some lucky fans.
