Isabel Lucas has laughed off reports she is Jake Gyllenhaal's new girlfriend - insisting the pair's relationship is "purely platonic."
The Brokeback Mountain star was rumored to have moved on from his relationship with Reese Witherspoon by sparking up a romance with the Australian actress, after they were spotted enjoying time together in Montreal, Canada in April.
However, the Transformers: Revenge of the Fallen beauty insists there is no truth to the speculation.
She tells JustJared.com, "We're just friends! Our relationship is purely platonic."
