Carrie Underwood ‘Worries’ About What Mike Fisher Does With Pals When She’s Touring

Fan are thrilled Carrie Underwood is returning to American Idol — the season four winner is rejoining the show as a judge — but fellow panelist Luke Bryan is more excited he’ll now be able to buddy up with Carrie’s pro hockey hunk husband, Mike Fisher.

The former NHL star, 44, is a hero to country musicians like Luke, 48, and Jason Aldean, 47.

"The Nashville guys love that Mike is all man, and he tells them stories about getting teeth knocked out by an elbow on the ice and his hunting adventures in the Great White North,” an insider exclusively spills to Life & Style. “He’s a different kind of macho man than they’re used to in the country music industry.”

At the same time, the "All-American Girl" singer, 41, is happy her man is palling around with Luke and Jason, whose son plays in the same youth baseball league as her and Mike’s boy, though spies say she’s also a little wary.

"Carrie loves that the country music guys gravitate toward Mike — it makes her cool by association,” a friend dishes. “But she also worries about what they might be up to when she’s out touring — all she can think of is her nice living room back home strewn with empty beer bottles!”
