Mariah Carey returned to the Billboard Music Awards stage for the first time in 17 years on Sunday night, but unfortunately for her, her performance wasn’t a big hit with her fans back home. While some Twitter users labeled the 45-year-old singer and newfound Las Vegas headliner’s performance at the 2015 show a hit, others had some not-so-kind words for the hitmaker.

Mariah, who is currently recovering from a case of Bronchitis, sang her new single "Inifinity" and her hit "Vision of Love" at the show.

Here’s what Twitter users have been saying about Mariah Carey’s performance at the 2015 Billboard Music Awards:
