The `Gossip Girl` star - who is believed to have previously dated co-stars Jessica Szohr and Leighton Meester in the past - is a strong believer in "intoxicating" love, but does believe a lasting relationship has to be based on more than lust.
He said: "It`s incredible, it`s intoxicating. To fall in love with someone at firstsight is fine, but in order to have a working relationship you need to realise that love is just one thing in a whole relationship."
The 23-year-old star has previously revealed he has a crush on singer Cheryl Cole, but he now believes too many men are interested in the British star - who has been romantically linked with Black Eyed Peas member will.i.am and dancer Derek Hough since splitting from now ex-husband Ashley Cole last year - and thinks she may need some time away from the spotlight.
He told Britain`s Cosmopolitan magazine: "Everyone is obsessed with her right now so it`s freaking me out. I think she needs to chill out, disappear and give me a call."
Discussing his dating style, the handsome star reveals he likes to be confident but not cocky.
He said: "You have to have a degree of confidence. I`m not uber-confident in that respect, but if you like someone you`ve got to go for it because if you don`t ask, you`ll never know."
The full interview with Ed is available to read in Cosmopolitan magazine from 7 February.
