Teen sensation Demi Lovato has denied her pal Joe Jonas is secretly dating country star Taylor Swift.

Jonas and Swift were romantically linked after the blonde beauty had a guest spot on the Jonas Brothers' new music video.

Reports of a relationship were fuelled after Jonas was spotted supporting the singer at her gig in West Palm Beach earlier this month.

But Lovato, who is supporting the Jonas Brothers on their current U.S. tour, is keen to laugh off reports of a romance between the pair - even if they would make a great couple.

She tells Usweekly.com, ""They would look good together, but too bad they're not. They just get along."

And when asked if she had her eye on one of the young Jonas hunks, she added, "I'm definitely not dating anyone!"

Lovato dumped former beau Cody Linley so she could join the Jonas Brothers on their cross country U.S. road trip.
