Taylor Swift stalks her former boyfriends.

The “Love Story” singer – who once wrote a song blasting former flame Joe Jonas of The Jonas Brothers – likes to spy on her exes — just to keep up with what they’re doing.

“In my spare time I like to drive past my ex-boyfriends’ houses. I’m not like throwing eggs – I just like to check up on them. Everybody does that – it’s just that nobody admits to it!”
