The cricketing great and sponsored poker player has been busy on the social networking site since joining up earlier this year.

A quick browse through his posts reveals he has tweeted to the likes of Lady Gaga, Lily Allen, Kylie Minogue, Lance Armstrong and Richard Branson.

But Warne's keenness hasn't always been received with the equal enthusiasm.

Warne's tweet to Branson - "Hello mate, its shane here how are you buddy ? whats news your side???" – is yet to receive a reply from the billionaire.

But plenty have responded, including Dannii Minogue, Delta Goodrem and a slightly sceptical Andy Roddick.

"hey shane! got your first twitter messages, but didnt know if it was u or not.... hope all is well buddy," Roddick tweeted back.
