Katie Holmes can sing and dance -- but she won't be appearing on Glee any time soon.
A rep for the actress, 31, tells UsMagazine.com the rumor -- which first appeared in the National Enquirer -- is not true.
Reports surfaced after Holmes filmed The Romantics with Dianna Agron, who plays teen mom (and former mean girl cheerleader) Quinn Fabray on the Fox series.
Last summer, Holmes performed Judy Garland's "Get Happy" on an episode of So You Think You Can Dance.
Tom Cruise -- who recently busted a move as Les Grossman at the MTV Movie Awards -- has said he admires his wife's footwork.
"I can dance a bit," Cruise -- who paired up with Holmes to perform "Whatever Lola Wants" at a charity event in May -- told Us. "My wife's a dancer, so I like dancing."
