Maddie & Tae's Maddie Marlow is prepping to marry fiance Jonah Font later this year, but it sounds like he may have competition.

Carrie Underwood's 4-year-old son, Isaiah, may have a crush on the "Girl in a Country Song" singer, his mother reveals.

"This morning my 4-year-old, who hates wearing jeans, asked to wear jeans so he could 'look cute for Maddie,' Underwood tweets. "He also asked me to fix his hair and to get him some flowers that he could give to her."

"Don’t you break his heart, Maddie Marlow!" she adds.

"I seriously could've cried," Marlow admits in her response, also via Twitter. "My heart just about exploded. y'all raised the sweetest boy! Goes to show what a great example you and your hubby set for your boys."

She hashtagged "new tour boyfriend," showing that she's in on the joke and happy to accept.

In the realm of broken hearts, Maddie & Tae currently are currently performing their new single, "Die From a Broken Heart" on the 2019 Cry Pretty Tour 360 alongside Underwood and Runaway June. The tour kicked off with three sold out shows in Greensboro, Birmingham and Little Rock.

"I can’t wait to tell my kids one day, 'I went on this badass tour with Carrie Underwood and it was the best tour you've ever seen,'" Marlow told the Tennessean in an interview earlier this year. "I feel like this tour is doing something so special, like, 'Don't miss the party. We’re having a party over here, join in. Join the girl party.'"

Well, a girl party plus one: Isaiah.
