Best friends Rihanna and Katy Perry hit the town for a girls’ night out last night, leaving the Rude Boy singer ‘feeling like a f******* rock star’, she tweeted afterwards.
Rihanna posted on her Twitter page after the crazy evening: ‘Just had fun wild night out with my bff @katyperry! Love u barec***!!! U always make me feel like a f****** rockstar!!!!’
The faul-mouthed singer began her evening by performing her new single California King Bed live on American Idol.

Full pockets: Katy Perry was snapped in a car when leaving the pizza eatery, holding a $100 bill in her hand

And after wowing the audience with her tune, she met up with Miss Perry for a pre-clubbing meal at Mozza Pizzeria in Los Angeles.
The ladies needed a bite to eat before heading to Voyeur Nightclub in West Hollywood, where they danced up a storm until 3am.
The club is a favourite hotspot for celebrities such as Joaquin Phoenix and Rihanna and Katy appeared to have a night to remember in the venue.

Rihanna, 23, resembled Jessica Rabbit as she headed out in a low cut, thigh high red dress and matching red silk peep-toe heals.
Her flame haired bouffant matched the outfit perfectly and she accessorised with a brown snakeskin handbag and an extravagant diamond necklace.
While Russell Brand’s wife Katy was spotted in a car leaving the pizzeria in a pink and purple blazer, brown hair ribbon and enormous fake eyelashes.
The 26-year-old was snapped holding a $100 bill, which was no doubt put on the bar tab at Voyeur.

She then slipped on a pair of sunglasses and reapplied her red lipstick as the car took off.
The pop stars appeared to be joined by some other friends on the night out, one of which sat with Katy in her car, while a male friend joined Rihanna in hers when she left the club at 3am.
While on American Idol earlier in the night, Rihanna let the audience in on a secret from her upcoming summer tour.
'We've designed the stage and we have two sections on the stage where fans can actually be in the show and on the stage, closer than they've ever been,' she told host Ryan Seacrest. 'It's real VIP.'
Meanwhile, as Katy enjoyed a wild night out, her husband Brand was in Sydney, Australia.
He tweeted on on arrival: 'I'm in Australia - the Essex of the world. I feel at home. Plus my criminal record is NUFFING here.'
