Rihanna, who is performing at tonight's Brit Awards, has collaborated with the R&B star on a remix of his new single Turn It Up.

But the pair have also come together for
an X-rated remix of her song Birthday Cake – which includes a lewd cameo from Brown.

The first line of the song Brown raps: 'Girl I wanna f*** you right now. Been a long time, I've been missing your body.

'Let
me turn the lights down, when I go down it's a private party, ooh, it's
not even her birthday but I wanna lick the icing off.

'Give it to her in the worst way. Can't wait to blow her candles out.'

Rihanna also repeats the refrain:
'It's not even my birthday, but you wanna put your name on it, oh baby I
like it, it's so exciting, don't try to hide it, I'm gonna make you my
b****.'

Brown reunite on remix called “Remember when money was more important
than you hitting me”'

level by tweeting out a version of his single Turn Up The Music that
features her own vocals in the background.

She wrote: 'Turn upt he music remix #RihannaNavy #Teambreezy enjoy!!!'

Though she doesn't seem shy about letting the world know she and Brown are on good terms, she did, after all, have something to promote.

The two have taken massive steps in recent weeks to becoming friends again.

Just one week ago, Chris snuck into her birthday party in Los Angeles.

While Rihanna was spotted in London
today in another racy get-up, Chris was pictured leaving his Miami hotel
wearing two blingy gold necklaces.

Brown is currently enjoying a sunny
break in Miami with with girlfriend Karrueche Tran, who showed off her
bikini figure as she relaxed on the beach.

TMZ reports that Karrueche is not
concerned about the reports Chris is heading for a union with Rihanna or
that he turned up to her birthday party last week.

Apparently the loved up couple are now living together and Chris whisked Karrueche away to Miami to celebrate Valentine's Day.

Sources have told the site that Chris
tells her every day how much he loves her and has no plans to leave her
for the Barbadian songstress.

Chris, who won his first Grammy
earlier this month, has come under backlash by some who don't believe he
should have been forgiven and allowed back into the music industry
after he assaulted then-girlfriend Rihanna three years ago.

Country singer Miranda Lambert had
taken to her Twitter page to slam the singer after he won the award for
Best R&B album for F.A.M.E.

'I don't get it,' she wrote. 'He beat on a girl.'

She
also brought him up during her concert at the University of
Massachusetts on Thursday where she produced a large poster with the
words, 'Take notes Chris Brown' scribbled on it just before she sang her
song Gunpower and Lead.
