Justin Bieber got fans riled up after he appeared to throw shade at his ex-girlfriend Selena Gomez.

At his 29th birthday party celebration, the singer shared a souvenir with a cryptic inscription

It read, "I'm so thankful that I didn't end up with what I thought I wanted."

Some fans described it as "petty" and called him "brainwashed."

A few other fans took a different stance, defending the singer's action as him being grateful for how far he has come.

Amid the outrage on social media, Selena took to TikTok to ask her fans to be "kind."

Selena said, "Please, please be kinder and consider others mental health."

The singer later shared on the platform that she was taking a break from social media.

Selena's decision may have been influenced by her ongoing feud with Bieber's partner, Hailey Bieber.
