no they do that cause they wanna show people that there in love.DUH
It sucks that paparazzi follow and harrass people like that. Like...what's so cool about seeing them walking? Or getting out a car? Or EATING?! I dont understand the paps...
I guess they have nothing better to do than stalk people's lives. Poor Selena...obviously she doesn't want her picture taken. DUH!
