As expected, Jay-Z joined Rihanna on stage at Brixton Academy last night as she launched her new album 'Rated R'.

It was Rihanna's first show since being assaulted by her then boyfriend Chris Brown in February and it didn't disappoint.

Wearing a mask and studded oufit, Rihanna came on stage and debuted largely tracks from 'Rated R' during the opening of the set, including recent single 'Russian Roulette'.

After being joined by Jeezy on 'So Hard', the 45 minute set climaxed with the arrival of Jay-Z on stage for 'Run This Town' and the ultimate 'Umbrella' which saw crowd members hold umbrellas aloft in the air.

The whole show was streamed live online through Nokia. The set-list was as follows:

1. Madhouse
2. Wait Your Turn
3. Russian Roulette
4. Don't Stop The Music
5. Take A Bow / Disturbia
6. So Hard
7. Live Your Life
8. Run This Town
9. Umbrella
