Josh Hutcherson has sparked rumours he's dating Dianna Agron.

A source told the New York Post's Page Six column: "They were even on the dance floor together.

"They looked like a new couple still flirting."

However, a friend of the blonde beauty has insisted the duo are not an official item, although that could mean they are taking things slowly because Dianna split from her Australian beau Thomas Cocquerel in December.

The stunning actress struck up a relationship with Thomas, 25, last March and they were spotted getting cosy at the Coachella Music Festival near Palm Springs, California, in April.

Their romance appeared to step up a gear a few months later when the actor - who was born in Sydney - flew Dianna to his native country to meet his parents and extended family.

However, their relationship was short-lived as she called it quits just nine months later.
