Ariana Grande defends Justin Bieber's fast engagement and her own speedy romance

Ariana Grande on Sunday defended her fast engagement to Pete Davidson and reports of Justin Bieber’s fast proposal to Hailey Baldwin after a fan criticized their manager Scooter Braun.

Grande tweeted, then quickly deleted, her defense shortly after TMZ reported Bieber and Baldwin got engaged Saturday during their romantic getaway to the Bahamas.

“First Ariana get engaged to Pete Davidson and now Justin Bieber to Hailey Baldwin...the devil works hard but Scooter Braun works harder,” a fan wrote on Twitter. 

Braun, for those unfamiliar, is the talent manager of both Bieber and Grande.
