It wasn't too late for Justin Bieber to say sorry to JoJo Siwa. The singer faced criticism after a comment he left on social media for Siwa. Siwa posted on her Instagram account last week about receiving a colorful BMW convertible for Christmas. Mind you, Siwa isn't old enough to drive yet, but that's not what Bieber took umbrage with. Instead, the Biebs slid into Siwa's comments to advise her to "Burn it." CNN reports Some fans of Siwa's, along with her mom, took Bieber to task for the comment.
