RadarOnline has a short video interview with Ashley Green. In it she discusses her future love scenes but she is very careful in what she is willing to reveal:

Radar: Are we going to see you in some love scenes in Twilight?  We need to see you in an onscreen romance!
Ashley: Hmm, yeh.  There’s a bit of one. Actually I don’t know if I want to so that…You’ll see one, ahh yeh, you’ll see one coming up in my near future.
R: In Eclipse?
A: I’m not telling!  You have to go watch it!
R:Anything with Pattinson?
A: Ohh gross! I think all the Twilight fans would strangle me.
R: You are not really brother and sister.
A: We’re not, but we have that weird brother and sister…I think out of anyone the connection Alice and Edward have and because of their extra abilities, that would be weird.

Me, too.

Does that mean I may just get my favourite line in the entire saga in the movie?! When Jasper is talking about his history and then he and Alice reminisce about how they met and Jasper says ‘for the first time in almost a century. I felt hope.’ ?! I SO hope so, because I just adore that whole scene…and note to Melissa Rosenberg, if it’s not in there – fear me!!

i agree with cee… that part HAS to be in eclipse!!! and i NEED to see jasper in his military uniform! and her and edward? yuck! edward and alice have way too much of a sibling thing to do that! she better stick to her main man jasper!

I’m still bitter there is no Emmett backstory in the books. And therefore no Emmett/Rose love scene in the movies. Salty doesn’t even begin to cover it.

I loved what she said about a love scene with Robert Pattinson! She’s right the Twilight fans would probably strangle her! Funny!

Cee – If the leaked script is the real script prepare to be disappointed. I too will be so upset if the I Felt Hope line is left out.

Monkey Man’s Wife, I agree! I want some Rose and Em love going on!!!!
