It all began when automobile design and repair company West Coast Customs posted a photo to Instagram of Siwa's colorful BMW on Friday. According to E! Online, Bieber commented "burn it" on the post, not once but three times.
In response, Siwa's mom, Jessalyn, clapped back at the "Sorry" singer and wrote, "Burn your own things." The Nickelodeon star also responded to Bieber's criticism of her new ride and said that burning the car was probably "not the best idea."
Following Bieber's shade, Siwa retweeted a photo of Ariana Grande with the caption "what y'all mad about today?" The young starlet simply wrote "burn it."
Fortunately, after seeing Bieber's apology on Sunday, Siwa, who received the car as a Christmas present, replied to the "What Do You Mean" singer's tweet and said she would accept his apology, but on one condition.
"It's all good bro!" she wrote. "You can perform at my 16th birthday party and we'll call it good!"
