Wretch 32 says that he would be a "rubbish" TV judge because he is so indecisive.
The rapper, who performed alongside Jessie J at the BlackBerry BBM party in London, admitted he couldn't see himself on a judging panel for a TV show like The Voice or The X Factor.
"I'd love to be able to, but I think I'd be a rubbish judge - I'm very indecisive," he said.
The 27-year-old - whose real name is Jermaine Scott - added: "I know music, but at the same time, you have to make decisions. You have to be firm. I'm really indecisive and I don't think I would find it easy judging. I've never really had to judge before."
Wretch 32 said he might make a better mentor: "Possibly."
He previously told UK Yahoo that he has seen the BBC show.
"I'm watching The Voice and I think the best part is the banter between Jessie J and Will.i.am," he said.
