Rihanna strutted the blue carpet of the Smurfs movie premiere in Brussels, Belgium, on June 28, but it’s not the only “blue” thing she’s loving.

U.K. radio network Capital asked the superstar what her go-to karaoke song is in a TikTok clip, and she revealed that it’s “Burning Blue” by Mariah the Scientist.

Released on May 2 via Buckles Laboratories and Epic Records, “Burning Blue” is the lead single from the R&B singer’s upcoming fourth studio album. It peaked at No. 25 on the Billboard Hot 100, making it her highest charting entry on the all-genre songs tally, and recently came in at at No. 25 on Billboard‘s 50 best songs of 2025 so far list.

Rihanna, who produced Smurfs and voices Smurfette in the live-action animated musical film, also contributed a song to the Smurfs movie soundtrack titled “Friend of Mine.” Jon Bellion, the song’s co-producer, told Billboard that “Friend of Mine” came together during one of his writing camps at his vacation home in the Hamptons last summer. “So when do you nail the feel-good, family-friendly, high-taste, deep ‘90s nostalgia, that can also be played into the kids movie? Shoot it out into the world!” he said.

Tyla, Cardi B, DJ Khaled, Natania, Shenseea and more also contributed original songs to Smurfs Movie Soundtrack. The Smurfs hits theaters in the U.S. on July 18.

With blue being such a highly discussed color, does that mean RiRi and A$AP Rocky will be having another baby boy? Rocky hinted at what that their sons RZA and Riot Rose might be getting for their next sibling while talking to Entertainment Tonight on the carpet, while Ri was a bit more tight-lipped, teasing: “Let’s see if it’s a Smurfette!” she quipped to ET. “Could be a Papa Smurf, who knows?”
