Question to Kellan:
Are Rob and Kristen still going strong and do you think they're going to get married?
Kellan Lutz answer:
You know what, I haven't talked to them in a little bit. It's not really a question that i can answer 'cause i don't know them... But they seem adorable every time i see them and madly in love so. You know who knows.. Hope the best for them that's for sure.
