Guys, I heard the funniest thing today

My cousin who hates Gaga, who is actually one of
Jason Derulo's biggest fans, claimed that Jason Derulo headlined Twickenham Stadium before Gaga

and then went on to say that JASON DERULO is more successful/more popular than Lady Gaga because he's played more at clubs...i just, I couldn't, and he damn well that everything he said was a lie lol, he's just pressed over anything to do with Gaga, and the thing is, i like Jason but...
