Nine years without a trophy ended for Tottenham at Wembley on Sunday - and it seems that everyone wanted to be in on the act, reports the Daily Mail.
Justin raised his arms in joy alongside his heroes as skipper Ledley King held aloft the trophy.
Far from treating him as an unwanted guest, the players appeared to share their joy quite freely - goalkeeper Paul Robinson actually poured a bottle of champagne over his head.
"It was just a spur of the moment thing, a bit of a laugh," said Justin of his decision to invade the pitch.
"I couldn't hear what Robbo said when he poured the champagne over me - there was so much noise from the crowd that you couldn't hear a thing."
Justin handed himself in to the stewards following his 15 seconds of fame. "I was arrested and held for three hours before I was bailed. I don't know whether I'm going to be charged," he said.
So was it worth the trouble? "Look, it wasn't something I had planned to do," he said. "It was just a bit of a laugh, that's all."
