Robbie Williams has launched an online tirade against a former girlfriend who two-timed him.

The singer attacked the woman, named as Tina, after he spent two nights with her before she revealed she had a boyfriend.

He rants on his blog, "You have completely blown any trust I had for you. If I knew my girlfriend had been on a dinner and DVD night with another man I would be livid. I'm furious thinking about it!!!!!!! And it happened weeks ago".

He goes on to launch a personal attack on his former lover's looks:

 �She�s amazing from the front, but from the side she looks like a shed is about to land on her on a special delivery from Kansas�.

What a gent.
