Did Blake Shelton Really Just Tweet Adam Levine's Cell Phone Number?!

Country artist seemingly really went for it in the prank department ahead of Monday's performance episode of The Voice

Talk about your battle rounds.

Blake Shelton and Adam Levine—who are just as famous on The Voice for constantly ribbing each other and/or being at each other's throats as they are for being handsome, supportive and talented coaches—may have taken it to a whole new level tonight.

Or at least Blake did!

"@adamlevine… I just found the craziest thing in my phone!!! Your PERSONAL cell phone number… hope I'm not stupid enough to tweet it out…" the country artist teased his friend and rival before Monday's performance show.

"I'm seriously amazed at @blakeshelton's stupidity…" Adam countered, adding, "@blakeshelton your threats are so cute."

Meanwhile, Blake tweeted, "Ya'll! @adamlevine doesn't think I will actually tweet out his personal cell number… he's flirting with danger…."

An hour later: "I should do it right? Who wants @adamlevine's personal cell number??"

And then there it was: "HEY EVERYONE!!! Here it is: [phone number] @adamlevine's CELL NUMBER! Think I'm kidding? Try calling it!! Bitch!!!"

After which it was duly retweeted by The Voice host Carson Daly.

P.S. The line was busy.

P.P.S. Levine hasn't tweeted a response yet, but he may be busy making a few calls of his own.
