Ex-girlfriend Shar Jackson helps him party

On Friday night, Kevin Federline had a 30th birthday bash at Pure Nightclub in Las Vegas – the same place he celebrated his birthday last year.

Wearing a smart grey suit, Britney Spears’ ex celebrated with a group of 20 pals, including his family, attorney Mark Vincent Kaplan and ex-girlfriend Shar Jackson.

The group enjoyed themselves at a VIP table, reports People. Throughout the night, they sang along to tunes by Jay-Z, Kanye West and other hip-hop artists.

The club’s deejay also played Kevin’s own Lose Control.

Drinking Jack Daniels, the rapper grabbed the microphone to make a speech, wishing everyone ‘a good time’.

‘I lost my voice at the craps tables and I lost all my money,’ he rasped, before a friend dragged him away.

With his face smeared with birthday cake, Kevin left the club just before 2 am and headed back to his Caesars Palace suite.

Sons Preston and Jayden were being looked after by the nanny and a bodyguard.
