One of our spies spotted Twilight stars Ashley Greene and Kellan Lutz on Wednesday night at the "I'm Yours" hitmaker's concert at the GM Place Arena in Vancouver, where our fave vampire movie franchise is filming Eclipse.
"They were watching the show from the soundboard area," the eyewitness reports. "Toward the end of the show, Jason and a couple of guys in his band went out on a small stage and did a few songs right there at the soundboard so the [people in the] back of the arena were able to see him up close."
After the show Greene and Lutz hung out backstage, as did Friday Night Lights star Scott Porter.
