"Whether it’s fair or not, Harris is simply Too Famous to take a potshot at Bloom in that way without facing a backlash," says Marissa Martinelli. "It can be easy to forget that even among celebrities there are tiers of fame, but Harris has been in the public eye for almost 30 years; Bloom is a comparatively recent breakout whose show (Crazy Ex-Girlfriend), while excellent, is consistently one of the least-watched on television...There’s a hierarchy even among celebrities, and Harris was punching down. Going forward, he’s better off leaving the 'I don’t know her's to Mariah Carey."
