For Emmy Rossum, her relationship with Counting Crows singer Adam Duritz began with a Tweet.
"I was on tour with the band this summer. They invited me actually on Twitter," Rossum said Thursday on the radio show Valentine in the Morning. "That's how we met on a dare. They dared me to come sing with them a song that I'd never sung before ... So I ended up on tour with the band, and it was very, very fun."
