Singer Cody Simpson's model ex-girlfriend Gigi Hadid has denied rumors she is romancing Joe Jonas.

The former Jonas Brothers star and David Foster's stepdaughter sparked speculation of a relationship after they were photographed together on multiple occasions.

However, Hadid's representative has shot down the reports, telling Just Jared, "They're just friends and have been for years. Gigi is 100 per cent single and focusing on her career. Anything to the contrary is absolutely false."

Both Jonas and Hadid split from their longtime partners earlier this year (14), with the singer calling it quits with model Blanda Eggenschwiler, and Hadid and Simpson ending their year-long relationship in May (14).
