London, Sept 30: Poker Face hitmaker Antonio "L.A" Reid believes that his decision to drop singing sensation Lady Gaga from his record label is the worst thing he has ever done.

Reid, 55, signed her up while she was still a struggling singer, but later removed her from his roster when he was having a bad day.

"This artist came to my office... she played piano, she had on white go-go boots - like, all the way up to here, thigh high boots - she sat down at that piano, she played and she sang. When she was done, I said, 'You are an amazing artist, a true star, and you will change music,' and I signed her. Her name was Lady Gaga," the Daily Star quoted him as telling Access Hollywood.

"Then, a few months later, I got her demos, and it was a work in progress, and I was having a bad day. I'm telling you, I was having a bad day. And I said, 'You know what? I really don't like it. Let her have her freedom, let her go find her career.' It was the worst thing I've ever done," he added.

However, a month later, the X Factor judge and former Island Def Jam Music Group chairman redeemed himself by signing teen sensation Justin Bieber.

"I felt bad, but I swear to you, like a month later Justin Bieber came and redeemed me, so, you know, I survived it all. But I'm a little bit jealous, because the Twitter following, for example, the biggest ones are Bieber and Lady Gaga, so I would have felt like the king of the world! Instead I felt like half the king," he added. (ANI)
