Her ex-husband is rumored to be secretly engaged to his new girlfriend Gwen Stefani, but Miranda Lambert is officially beating Blake Shelton when it comes to announcing her own engagement.

Lambert took to Instagram over the weekend to share the news that she is officially getting married, but with a catch, since her fiance is not her boyfriend Anderson East, but is actually a six-year-old fan.

"I said YES! But he has to wait 25 years. This sweet boy Sebastian is a little gentleman #pinkring #proposal #mademyday 3jersey #spreadthelovetour," she captioned a photo collage of her being proposed to and then showing off the ring in a photo with the boy.

In the images, Lambert seems stunned when Sebastian drops to one knee with a ring box in his hand, and smiles in the second photo with one arm around him as she shows off the ring he gave her on her left hand.

Of course, it's not likely Lambert will wait the 25 years to marry her new fiance (which would put their respective ages at the time of the wedding at 31 and 57), especially since she is still dating East, who she went public with in January.

Lambert's first marriage to Blake Shelton ended after four years, and the pair announced their divorce in July of last year. Since then, he publicly began dating Stefani last fall.

Though Lambert's romance is more low-key and not constantly speculated on, Shelton and Stefani's relationship has been much more high-profile, and is constantly making headlines with speculation.

The most recent rumors have suggested that the two are secretly engaged and planning to announce their news in September, and that they aren't going to wait long to tie the knot, with plans for a Christmas wedding at Shelton's Oklahoma ranch. The reports have indicated that the couple is holding off on announcing their engagement until they've hammered out all of the details concerning their prenuptial agreement.
