Notice how he's started saying to other judge's acts.

"You know I'm a great fan of yours but..."

where he just used be complimentary to them.

I think it's pretty obvious he's getting worried and trying to sabotage everyone else now.

Ah well...he said he's competitive.

I used to like him, but he's just become a two-faced bitchy loser.

Hes sticking the knife into his own act. He said that Frankie isn't the best singer.
