Ashley Greene snuggles into on-screen love interest Jackson Rathbone in this preview of relationship tips in the December 2009 issue of Glamour UK magazine.

The duo joined up with costars Nikki Reed and Kellan Lutz for the interview where they dished on the meaning of love, soulmates and relationship deal-breakers. Check it:

Kellan on confidence in a relationship: “That’s so sexy to me. I also love a girl who’s switched on, like she knows how to book an airline ticket and get the cheapest one.”

Nikki on break-ups: “I remember my first break-up. I literally thought my life was over. Then you realize, it’s like a cut — there might be a scar but the pain will go away.”

Ashley on soulmates: “Gosh, I hope so. I’m a strong believe in chemistry [too]. It has nothing to do with what you want, just how your chemicals react with each other.”

Jackson on love and lust: “Lust tastes like tequila and love tastes like whiskey. Love burns for longer and warms you up on the inside and sometimes it makes you do stupid things. Tequila just makes you wasted.”
