Adam Levine managed to "offend" everyone on the set of The Voice recently because of his unwavering "immaturity".
The Maroon 5 frontman appears alongside Cee Lo Green, Christina Aguilera and Blake Shelton as a judge and mentor on the NBC TV talent show.
Adam took to his Twitter page to let fans know his and Blake's childish levels hit a new low during filming.
"I'm pretty sure @blakeshelton and I managed to offend every single person on set today. We were even more immature than usual... (sic)" he teased.
Blake recently admitted to having a man crush on his fellow voice coach, Adam. The singer joked to MTV that the burgeoning friendship between them is turning into something more for him.
"It's funny, 'cause I get on Twitter, one of my routines during the day, if I'm home is, I wake up, get a cup of coffee, turn on the Weather Channel and I'll look at what people are saying to me on Twitter on my phone, and it's always something about me and Adam, the bromance," he said.
"All I have to say is, it's true: I have a man crush on Adam. It blows me away people can pick up on that just by watching that on television. I want to kiss him. I want to kiss him so bad. I don't care if it's mutual or not. Can you honestly tell me that you don't have a little bit of a crush on Adam? He's sexy, is the word I'm using."
Meanwhile, Adam also addressed rumours he is starting up a new supergroup with Canadian sensation Justin Bieber.
Justin took to his Twitter page to update his fans on the situation.
"back in the studio tonight with my new #Supergroup @adamlevine @kennyhamilton (sic)," he wrote, before Adam joked about Justin's burly bodyguard getting in on the act.
"@adamlevine @justinbieber @kennyhamilton the best part is that Kenny is the singer. #pitchy (sic)."
Justin also updated fans on the members.
"big night in the studio tonight. glad to add my boy ryan from @onerepublic to our #SUPERGROUP (sic)" he explained.
Justin - who is currently putting the finishing touches to his third studio album, Believe - told his Twitter followers about hitting the studio with Adam earlier this week.
"Long night in the studio. Good seeing big bro Adam Levine - we got a big idea coming! new supergroup. Adam Levine I don't think the world is ready for this supergroup (sic)," he wrote.
