The rep claims recent rumours linking the stars romantically are far from true, including a new report suggesting the actress was overheard professing her love for her ex-husband Tom Cruise's Collateral co-star over the phone.

The spokesperson tells GossipCop.com, "These stories are untrue... Katie is not dating anyone.

"She was on phone with her daughter when she supposedly was overheard saying I love you... This gossip needs to stop."
