We were slightly shook when Liam came out and admitted that Harry's music wasn't his cup of tea, but in came JB to the rescue!!
After Harry's Carpool Karaoke with James Corden landed, Bieber took to his very own Instagram account to show his respect for Haz.
"Just watched Harry styles carpool karaoke!! Hilarious! Also congrats on the album, it sounds great !" he wrote.
God bless respectful, loving Justin Bieber.
Who knew he was such a directioner? And speaking of directioners... LIAM PAYNE TAKE NOTE. #StillNotOverIt.
