41. DJ Calvin Harris became a Twitter target of the 31-million-follower Lady Gaga after claiming on BBC Breakfast that the megastar refused to collaborate. According to Gaga's timeline, that was false. "Seems to be trendy lately to talk shit about "Lady Gaga" when your albums/singles drop," she tweeted. "Y'all should live off your own hustle. Never even emailed you @calvinharris I guess it's hard to believe I write + produce my music. Cuz I'm a woman I don't know about EDM right?"
