Now, Abbey has taken her heartfelt ballad to an even grander platform, leaving fans ecstatic.

Gracing the stage of Clarkson's talk show on Monday (May 5), Abbey performed her song accompanied by a live band. The lyrics are a testament to their bond, with lines like "the lion to my lioness, the milk to my Chardonnay. My prince charming doesn't bring me flowers, you know I'd rather have gummy bears any day," reports .

Further into the song, she reveals: "I know sometimes I'm in my head, but when I'm with you, I'm in the instead. No one treats me better, we're so good together. Will you be my boyfriend forever?"

The song concludes with a heartfelt declaration: "I wanna be your girlfriend forever."
