Dedrick is just not a fan of these famous claims.

In E! News' exclusive sneak peek at the July 24 episode of Claim to Fame, Dedrick and fellow contestant Naomi have an awkward run-in at breakfast after she greets him as Mr. Jackson, a nod to the apparent clue he dropped during conversation the night before.

It's a greeting that truly takes Dedrick off guard.

"Why would you call me Mr. Jackson?" he says during a confessional. "Johnson, maybe. I think I look more like The Rock. Don't you?"

However, according to Dedrick, there were even more guesses that took him by surprise.

"Whatever you just called me is f--king better than Little Richard," he tells Naomi, referring to Adam's previous guess of his celeb relative. "I don't want to f--king be called Little Richard man. You ever seen that brother? Call me Jay-Z before that."

And though this admission earned laughter from his housemates, Adam couldn't help but reflect on why Dedrick would be so offended.
