RiRi usually takes the Tube to go to the O2 Arena, but this time she decided to catch the helicopter. She and Melissa, her best friend, were photographed at a heliport in London yesterday (May 20), when they were on the way to Kanye West and Jay-Z’s “Watch The Throne Tour” — check the previous posts for more details.

RiRi was photographed at Boujis nightclub in London last night (May 20). She’s now on her way back to LA, where she will perform on American Idol finale this Wednesday!

UPDATE: Watch Rihanna and Kanye performing “All Of The Lights”:

After watching Jay-Z and Kanye West’s “Watch The Throne Tour”, Rihanna was spotted at DSTRKT Nightclub for the exclusive after party celebrating Roc Nation’s Ty Ty’s 40th birthday in London last night (May 19). RiRi tweeted:

Via The Sun: Jay-Z hosted the bash in London last night and security was so tight that guests were asked to bring photo ID — even though they were some of the biggest stars in the world. Jay-Z hosted the afterparty, held at the Dstrkt club, to celebrate his manager Ty Ty’s 40th birthday. A source said:

“This was the hardest party to get in to. Only 150 people were invited and every guest had to carry an appropriate form of identity or they were not getting through the doors.  Security wouldn’t have batted an eyelid about turning them away — if you didn’t show proof of who you were, you just weren’t getting in.”

Rihanna wasn’t the only guest who flew in especially for the party. Jay-Z asked his oldest friends in the industry to make the journey. They rubbed shoulders with a host of other big names inside. Kanye’s girlfriend Kim Kardashian, Rita Ora and her boyfriend, Kim’s brother Rob Kardashian, plus rappers Mr Hudson and D’Banj featured on the guest list. Gwyneth Paltrow, who took her two kids to Friday night’s Watch The Throne show, was also there.

The party kicked off at 11pm and Jay-Z did a mini set. His chef was flown over from New York and club staff were warned to have plenty of Ace Of Spades champagne. The guest list demonstrated the pulling power of the world’s biggest rappers, as have the London shows. All three have sold out and the opening night on Friday also attracted some big names in British music, including Cheryl Cole, and members of JLS and One Direction.

Princess RiRi and Jennifer Rosales, her friend/personal assistant, were photographed leaving their London hotel earlier today (May 19). Rihanna was later spotted at Jay-Z & Kanye West’s “Watch The Throne Tour”. Singer Rita Ora also shared a picture of them together, click here to see it.

Cheryl Cole will apparently feature on Rihanna’s new Sky Living show. The singer will make an appearance as a fashion adviser during the search for a talented designer, which also features Nicola Roberts and Henry Holland.

Cole visited the East London set of the show after returning from Las Vegas earlier this week, The Mirror reports. The winner of the programme will design a stage outfit for Rihanna, also the show’s executive producer, which she will wear when she headlines this year’s Wireless Festival.

“I am so excited to be working with Rihanna on finding a new British up-and-coming designer. I was so flattered when she asked me to work with her on this show,” Roberts has said of her new role. “I’m so excited for us to get started on finding a new up-and-coming British designer who just needs a chance, a little bit of help in getting their skills noticed.”
