AceShowbiz - Blue star Antony Costa has apologized after he was photographed urinating in a London street last week. The boyband singer was snapped relieving himself against a cashpoint in the U.K. capital during a night out and the photos were published in a tabloid newspaper over the weekend.

Costa has now spoken out over the incident, insisting he regrets his "stupid" actions. He tells Britain's Daily Mirror, "I was so mortified when I saw the pictures. No one wants to be seen like that. I would never, ever want to upset or embarrass my family or the band."

"I was on a night out, got a bit drunk and did something stupid. It's a mistake I'm not proud of and I am so, so sorry to anyone I have offended. I hope people can see this is very out of character for me and accept my apology. I hope people allow me to move on."
