Ahead of his stint as SNL host and musical guest on NBC this Saturday Jan. 24, "Boys Round Here" singer Shelton — who is married to fellow country superstar Miranda Lambert — revealed to E! Online, "I think there's a little part of Miranda that's really worried," about his hosting SNL.

He added that it's due to the fact his while he's great at parties, when he's piling on the laughs he begins "taking it too far into gross land or whatever," and Lambert is "the one that's always like, 'Blake! Blake, stop it.'"

"She won't be here when we do this and there won't be anybody," the singer laughed. "She's like a stage mom and she won't be here to go, 'Oh, I really don't think you should do that.'"

And in the Saturday Night Live promo with Cecily Strong he calls - as Huffington Postsay 'onscreen rival' - Levine a punk and calls him out, saying "look who's hosting SNL now, pretty boy."

Shelton, though, also took to The Tonight Show and, after watching host Jimmy Fallon impersonate his singing style on "Neon Lights" and "Boys Round Here" he revealed that he doesn't feel so warmly towards the new Tonight Show host,. "I seriously can't stand you," said Shelton.

Why do I come on this show?" he snorted disgustedly. Find out exactly why below.

The "Neon Lights" singer also took part in a new game called 'The Whisper Challenge', where Jimmy and Blake put on a pair of headphones with loud music playing: as one reads out a random phrase from the card, the other tries to guess what they're whispering.

Bracing myself for whatever kind of bullshit @jimmyfallon has planned for me tonight...

Some highlights include Shelton loudly yelling at Fallon and saying 'my pee pee's stretched out' when trying to guess 'Pumpkin Spice Latte', dealing with the phrase 'Cobra Kai'... and saying that Benedict Cumberbatch "doesn't mean anything!"

"He's nominated for an Oscar!" yells Fallon.

"This is the stupidest thing I've ever been a part of in my entire career," says Shelton in a voice full of regret. Coming from a man who has played alongside Bill Ray Cyrus at the 2009 Bayou Mullet Festival and routinely speaks to Adam Levine, that's quite a claim.
