Ashley Greene jokes she could be the first of her friends to get married.

The Twilight actress, 23, doesn’t believe marriage to be an essential part of every committed relationship, but she could change her mind.

“I’m indifferent about marriage,” she said. “I think sometimes people get married so they can say they have that person forever, but a ring doesn’t ensure that you’ll stay together.”

“Watch, now that I’ve said that I will be the first of my friends to get married!”

It was recently reported that Joe and Ashley will be spending Christmas together.

According to Us Weekly, Ashley will be taking Joe back to her parents’ house in Jacksonville, Florida for the holidays, which should surely prove how serious they are about each other.

“It started out as, ‘OK, we’ll go on a date,’ and now they’re head over heels!” a source told the site.

The middle Jonas Brother and the Twilight actress started dating back in August and have been pretty much inseparable ever since.
