Blake Shelton isn't just owning up to having "one of those weeks" after news of his divorce broke, he's also ready to talk pageant life.

The 39-year-old country star fessed up to ET about his mom starting him in pageants as a little boy and, like most of us, pal Brad Paisley couldn't believe his ears.

ET dug up video of The Voice coach singing during a Valentine's Day-themed beauty pageant in 1985 when he would have been around 8 years old. Shelton confirmed that he had to join a girl pageant as there were no pageants for boys, but he quipped that he was "picking up chicks."

While Shelton's main focus was the performance, he wasn't able to pick and choose which categories to participate in.

"There was a talent portion of the pageant," Shelton explained. "In order for me to sing in the pageant, like my mom wanted me to, I had to do the evening wear and all that crap."

"This is the greatest thing I've ever heard," Paisley said.
