Carrie Underwood was overwhelmed to have won Entertainer of the Year at the American Country Music Awards on Sunday night, but the moment did turn a little mortifying when she made a sexual reference joke to wanting to see Matthew McConaughey’s "boots" in her acceptance speech.

The Texas-born actor presented Underwood with the big award, but before his official duties he entertained the audience with a story on how he and his brother once took a road trip thru Texas to see Dwight Yoakam perform. While there the brothers tried to "pick up" a few ladies by telling them that they made a livin’ exclusively custom-making George Strait’s boots.

"We’re like, ’Oh yeah. Say, as I a matter of fact, out in the parking lot, in the trunk of our white Corvette, we have the next year’s new edition white ostrich quill George Strait signed series that he’s gonna wear on tour next year.’ And they got pretty excited about that and said, ’Well, can we see? Can we see? Can we see?’" McConaughey told the audience. "And we obliged … Point of the story is, we got lucky that night. Thank you, George."

After taking the trophy from McConaughey, a tearful Underwood caused jaws to drop when she said:

"I don’t know what to say. I got nothin’ … I want to see those boots, Matthew."

"I’m so embarrassed, I totally embarrassed myself. I just blanked," Underwood said backstage, burying her head in her hands. "You want to say something eloquent in a moment like that and I embarrassed myself. I’m sorry Matthew, I’m sorry to my family. I’m totally embarrassed."

Mathew gets that all the time. He doesn’t even have to use the boot line anymore, he just walks up to girls and says "hi I’m
Matthew McConaughey." That’s probably how he met Camila Alves.
