Blake Shelton is head-over-cowboy boots for his bombshell wife Miranda Lambert, and despite rumors of infidelity, there's no sign of trouble in paradise for country music's cutest couple. However, Blake's only human, which means he's just as prone to celebrity crushes as we are — but this particular crush we didn't see coming!

In a new behind-the-scenes clip from The Voice Season 5, host Carson Daly joins the OG coaches to reminisce about the first time they all met. In a moment of complete candor (because that never happens) Blake admits that he could hardly contain himself when Christina Aguilera showed up.

"My heart pounded when she came walking in. Remember that?" Blake recalled. "Oh my god, I had such a crush!"

Don't worry, guys — we're sure he was talking about her "Dirrty" days, eons before he'd even met Miranda. And, honestly, who hasn't had a crush on Xtina at one point or another? Either way, Blake's crush seems to have been short-lived because after working with the pop star on NBC's hit competition show, his feelings did a 180.

"Now my heart pounds out of fear," Blake joked as Christina threw her head back with a menacing laugh.

Don't be such a drama queen, Blake. You live with a woman who sings about loaded shotguns, for cryin' out loud!
