After putting on an energetic two-hour concert, you couldn't blame Rihanna for wanting to head back to her hotel for a much needed rest.
But after performing to a sell-out crowd at London's O2 Arena, it appeared the Bajan singer was so fired up she headed off into the West End for a spot of clubbing.
With youth on her side, the 22-year-old singer managed to find the energy to party at Mahiki in Mayfair until 4am this morning.

Wearing a nude mini-skirt and denim blouse, the Umbrella star looked positively demure compared to her risqué on-stage outfits.
During her two hour concert, Rihanna flashed the flesh in a variety of kinky outfits, including a latex body and nude bodysuit.
She performed all her biggest hits from her four years in the charts, including SOS, Shut Up And Drive, Disturbia, Unfaithful and her most recent release Rude Boy.

Last night marked the singer's first gig in London after opening the UK leg of her Last Girl On Earth world tour in Birmingham on Friday night.
Rihanna's 62-date tour kicked off in Belgium last month and is set to finish in Syracuse, New York on August 28.
Last week, she took time out of touring to film a romantic video for her new single Te Amo in the grounds of a French château
While Rihanna has been touring, she's been missing spending time with her new boyfriend, baseball player Matt Kemp.
The Los Angeles Dodgers player recently broke his silence on their burgeoning relationship, saying: 'Yeah, that's my girl.


'She’s just a fun person. I love to be around her…She’s definitely a great person in my life and I’m happy I’m with her.'
Kemp is Rihanna's first relationship since her high-profile split from R&B star Chris Brown, after he assaulted her on the way home from a pre-Grammy party in February 2009.
