Background and concept
"The single after this is called 'Shimmer' and that's where we start to love ourselves [again] ... like, 'I don't sweat, I shimmer!' Like, 'I got this!'"
In 2026, Meghan Trainor made her return to music with the lead single of her seventh major-label studio album, Toy with Me, on November 12, 2025, "Still Don't Care", followed by the Christmas single "Gifts for Me" on November 21. Trainor would eventually go on to tease and release the song "Get In Girl" as the second single. Although soon after, she revealed that a song called "Shimmer" would follow as the third single from the album.
Trainor co-wrote "Shimmer" with Caroline Pennell, Grant Boutin, and its producer Gabe Yaron. According to Trainor, the song is about self-worth and "lov[ing] ourselves"; KJYO noted that the song "will help all those down get back up!" The music video for "Shimmer" accompanied the release of Toy with Me, both happening on April 24, 2026.
