Maddie & Tae’s Maddie Font once held Taylor Dye’s baby for a whopping eight hours: “I’m a baby hog"

Maddie & Tae are more than just bandmates -- they're also best friends. So when Maddie Font first met Taylor Dye's baby girl Leighton, she immediately slipped into aunt mode.

"I'm such a baby hog," Maddie admits in an interview the duo recently gave to ET Online.

Right now, the tour bus in question is for Maddie & Tae's CMT Next Women of Country Presents: All Song No Static Tour, a trek that will continue throughout this month. It's also a busy time for the pair in terms of new music releases, as their Through the Madness: Vol. 2 project drops Friday.
