The Twilight heartthrob is known to shy away from publicity but being such a huge star it's inevitable he's had his fair share of run ins with photographers.
Chatting with the new issue of Esquire magazine, the gorgeous actor admitted that his mind briefly goes to panic mode when he sees a large group of paps outside his home.
"Whenever I see a bunch of paparazzi hanging out, I always think, 'Oh God, what have they found out!' Oh, THAT love child! I totally forgot!"
British-born Robert said he didn't really understand why photographers would want to follow him and suggested maybe they just had "periods where you're assigned, 'this is the guy to follow.'"
Or maybe it's because you're an incredibly handsome Hollywood star who happened to play the lead role in one of the most successful recent movie franchises?!
He speaks in the interview about how paparazzi were part of the reason he had to leave his last home, a gorgeous mansion in Hollywood.
"They photographed anyone who came up to the gate, anyone who rang the bell, and they followed any car that came in and out. I used to dress up my assistant as me, and get him to drive off with like five cars following him around for hours."
R-Pattz always manages to keep himself out of the spotlight - even when his personal life is what EVERYONE is talking about.
Two years ago he found himself at the centre of unwanted attention when then-girlfriend Kristen Stewart cheated on him with a married film director. But, despite the fact he was promoting a movie at the time of the scandal, he refused to be sucked in, focusing on his professional life instead.
