Justin Bieber might be a little salty about Selena Gomez's new relationship with The Weeknd.

With rampant reports of Gomez romancing The Weeknd, many have wondered what her ex-boyfriend, Bieber, thinks about it. Bieber conducted a live event on his Instagram page Sunday night and certainly raised a few eyebrows regarding his thoughts.

Bieber was asked what his favorite song was at the moment, to which the young singer replied, "Umm ... 'Starboy' by the Weeknd." He then burst into laughter, adding, "We've got to end it now. Oh, that was too funny. Bang, bang!"

Bieber previously threw some shade at The Weeknd, telling TMZ in January, "I can't listen to a Weeknd song. That s-'s wack."

Gomez dated Bieber on and off from 2011-14.

The Weeknd performed at the Grammys Sunday night with Daft Punk, collaborating on "Starboy" and "I Feel It Coming". He reportedly got close with Gomez at the Grammys after-party.

Bieber chose not to attend the Grammys despite netting multiple nominations, including Album of the Year for Purpose and Song of the Year for "Love Yourself". TMZ reported that Bieber was not going to attend because he "doesn't think the Grammys are relevant or representative, especially when it comes to young singers."

Bieber, who was also nominated for Best Pop Solo Performance for "Love Yourself" and Best Pop Vocal Album for Purpose, wound up losing all of his categories anyway. Adele actually won all of his categories, either for 25 or "Hello".
