Before Tim McGraw pulls into the epicenter of country music tonight on CMT Radio Live with Cody, he dropped by The Ellen DeGeneres Show with some raw revelations.

The country megastar revealed while he owns only one pair of Ellen’s celeb-popular underwear, sometimes he doesn’t wear any undergarments at all.

“These pants were too tight to put underwear on,” Tim said. “Now I’ve really embarrassed my daughters. What was I supposed to say?!”

He may have gone commando for the show, but the daytime hostess surprised Tim with a basket full of his own Ellen underwear before the interview wrapped.

Watch the full interview above. Tim also helped Ellen play a harmless prank on an unsuspecting guitar tuner. See that hilarious clip below.
