Sediuk, who was slapped by Will Smith on the Men In Black 3 Moscow red carpet last year after kissing the star, told The Hollywood Reporter that he got a ticket for the ceremony from friends after his channel failed to get accreditation.
"My purpose was not get a seat and enjoy the view and enjoy the singers. Actually, I'm a reporter and it was part of my report," said Sediuk.
"I've interviewed many A-list, so it's not like, 'Oh my gosh, I'm here'. I was quite excited because next to me was Sting, Justin Timberlake, Beyoncé... it's a really cool experience, yeah?"
He added: "The idea to come on the stage was last minute - last second.
"When I heard Adele - to be honest Adele is my favourite singer. I know all of her songs - like 'Set Fire To The Rain' - everything.
"I had this idea to go on stage and say what I sad... I pretended the award was for me!"
Sediuk said: "My purpose is to entertain and to show a different emotion of celebrities. I'm not a crazy guy. I just think differently."
Sediuk was arrested and spent the night in a jail cell. He was released yesterday (February 11) after being changed with trespassing and given a March court date.
