Ashley Greene Works Off Her Stress With a Smile

Either Ashley Greene had a good workout or was going to visit boyfriend Joe Jonas because she sure seemed happy on Tuesday! Ashley walked out of her gym in Sherman Oaks, Calif. early in the morning after a nice workout, ready to greet the day. The Twilight star has been caught up in rumors regarding Demi Lovato's entering rehab, but they don't seem to be getting her down.
