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.”
Their relationship came to light this fall after they’d been spotted together multiple times. Rossum, 23, split from husband Justin Siegel in August – though her marriage was not widely known about.
