Miranda Lambert Gets Engaged -- But Not to Boyfriend Anderson East!

We can't wait to get for an invite to this wedding in '25 years.'

Miranda Lambert's love life has really done a 180 from last summer!

The country crooner was proposed to just moments before she hit the stage at MetLife Stadium in East Rutherford, New Jersey, on Saturday, but the sweet request didn't come from her boyfriend, Anderson East.

Rather, it was an adorable 6-year-old boy named Sebastian who popped the question.

"I said YES! But he has to wait 25 years," the "Vice" singer jokingly captioned an Instagram collage shared on Sunday. "This sweet boy Sebastian is a little gentleman. #pinkring #proposal #mademyday #jersey #spreadthelovetour❤️."

How sweet is this? The look on Lambert's face is everything!

Once she hit the stage, the 32-year-old singer even shared the good news with the crowd, revealing, "I got engaged today," and flashing her new pink ring.

"When he came to my meet and greet, he got down on one knee and he was such a gentleman," she announced before launching into her 2007 hit, "Gunpowder & Lead." "It may be my favorite proposal ever. But it made me think about this song, because girls, we deserve that. So that being said, thank you, Sebastian. I'm gonna leave you with a pretty little love song."

The Texas native has been dating East since late last fall. No word on if the R&B singer will be taking a cue from little Sebastian and getting down on one knee anytime soon!

While Lambert was performing in Jersey, her ex-husband, Blake Shelton, was professing his love just one state over that same night. The Voice coach surprised the audience at the annual Apollo in the Hamptons fundraiser, dueting with his girlfriend, Gwen Stefani, on their song "Go Ahead and Break My Heart" to kick off her scheduled set at the charity event.

Lambert appears to be over her ex, however. Earlier this month, she rocked a T-shirt with East's name on it during the Irvine, California, stop on her Keeper of the Flame tour. Find out more about that telling tee in the video below.
