Halsey is proving just how much of a die-hard Lakers fan she really is.

The singer was not having it after last night’s western conference game when Grizzlies player Desmond Bane came after LeBron James with his rude demeanor.

The 23-year-old Memphis guard was evidently chirping throughout the entire Lakers’ home game against his opposing team. The match heated up to the point where James shoved Bane for his endless running mouth.

Halsey, who was sitting courtside throughout the action, had a few things to say to Bane after the aggressive game.

The award-winning singer took to Twitter to express her anger, writing, “Courtside observations: Bane got an unnaturally loud and rude big a** f***in mouth.”

Grizzlies’ fans quickly responded to the since-deleted tweet, firing their own shots at the unimpressed “Eastside” singer.

“Bruh shut the f*** up,” Halsey replied to one fan. “This man LeBron almost had to give him a masterclass in decorum.”

“Everyone s*** talks but word on the court was ‘he’s a problem,'” she said.

Bane responded to Halsey’s comments by expressing his thoughts through a few laughing emojis and a thumbs down. He later deleted the tweet.
