(Flynet)

Robbie, didn't your momma teach you better than that? He's a catastrophe, but a sexy one. He looks like a sweaty crushed velvet and cocaine Boston Terrier but there's just something about him. He recently read a chick he was dating via the Internets.

The singer, 33, who has just come out of rehab in his battle against drink and drugs, attacked the woman, named as Tina and believed to be a real estate worker, after he spent two nights with her before she revealed she had a boyfriend.

Robbie needs a hug: The single singer launched a tirade againts a cheating former lover, an estate agent known only as 'Tina'. In his online message, he rants: "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!!!!!!! And it happened weeks ago."

He continued in the rant on his blog: "I was p***** off for all of 20 minutes...I liked her and I expect more from her and women in general."

Don't we all? I expect them to be my fantastic friends and have pretty hair and to never, ever show me their honeypots. Thanks, ladies. I'll do the same for you. Dinner and DVD night? That's...uh, wow. Boring. I know he's fresh out of the booze pokey but can't he take her for a walk on the boardwalk or something? Dude, step up your game.
