Taylor Swift worries about being in the wrong relationship

The 20-year-old singer ' who is rumoured to be dating actor Jake Gyllenhaal and whose ex-boyfriends include Taylor Lautner and Joe Jonas ' is not prepared to be with someone she believes is wrong for her.

She said: "It's a little strange that I'm typically single a lot. I have a phobia about being in the wrong relationship. So as soon as I establish it's not the right one, I don't want to waste their time."

Despite her relationship worries, Taylor is still 'fascinated' by love, though admits she has only recently realised there is no 'strategy' to finding romantic happiness.

She added to Allure magazine: "Relationships are fascinating and riveting and completely unpredictable. For me, love is everything.

"I used to think there were all these rules for making people like you. I was filled with advice! I'd tell my friends things like, 'Don't accept that apology! That isn't sincere!' or 'He hung out with his ex-girlfriend? Get rid of him.'

'But love is never that simple. Now I'm finally getting the idea it's the one thing I don't need to have a strategy for.'
