A U.S. tabloid last month (Jul09) alleged Year One star Cera had pulled the plug on their relationship so he could make the most of his newfound fame and date other girls.
Yi appeared to back up the reports during an appearance on the Tonight Show last week (03Aug09) when she performed a break up song, telling the audience, "It's kind of a sad song about my boyfriend breaking up with me. What can you do about it? Write a song about it... and try to win him back.
But in a new interview with Moviefone, Yi claims the pair have never been an item.
She says, "We weren't dating at the time... or ever.".
