Chris Brown 'threw up' after party

Chris Brown 'threw up' after his birthday party on Saturday night (04.05.13).

The 'Fine China' singer - who turned 24 today - revealed he got 'too wasted' during his celebrations in Las Vegas after securing a lucrative deal with 1 Oak nightclub to host his bash there.

The R&B star tweeted: 'Do too wasted at the party. Threw up crazy!! Lol!'

A source also told HollywoodLife.com that Chris attended Floyd Mayweather Jr. and Robert Guerrero's boxing match at the MGM Grand Garden Arena before moving on to the swanky hotspot with his entourage.

Chris tried to convince his on/off girlfriend Rihanna, 25 - who is currently on her 'Diamonds World Tour' - to join him for the night after she was forced to postpone her concert in Brooklyn, New York on Sunday because the Brooklyn Nets need the venue to compete in the playoffs.

An insider previously said: 'That's his number one and he wishes she could be with him on his birthday just like he was with her.

'But that's just how it goes sometime. They can't be together every second.'

But the 'Stay' singer opted to stay in New York.
