As if having the support of Gary Barlow and Simon Cowell wasn't enough, David Cameron's got a new fan in the form of Arnold Schwarzenegger.

Schwarzenegger - who took time out from action films to become Governor of California between 2003-2011 - took to Twitter to give his friend a firm digital handshake.

The actor-turned-politican, who represented the Republican party in the Californian elections, clearly supports Cameron in a political and personal sense.

Terming the re-elected PM a "friend", perhaps Schwarzenegger is hoping to get an invitation to 10 Downing Street in the near future.

Arnie, joins an eclectic line-up of celebrities, including Peter Stringfellow, QPR player Karl Henry, Dragons Den star Kelly Hoppen and business person and TV personality Karren Brady, to warmly congratulate Cameron.

Stringy was over the moon at Cameron's victory, and even threw a party at his nightclubs, offering free lap dances and shots to fellow Tory supporters.

Queens Park Rangers midfielder Karl Henry was pretty happy, too - as were Karren Brady and Kelly Hoppen.
