Josh Hartnett and Kirsten Dunst are being touted as the hot new couple in Hollywood after they were spotted making out at the the Sundance Film Festival.

The stars fuelled relationship rumours when they got physical after watching a performance by supergroup Camp Freddy at the Park City, Utah event.

A source tells People: "They were making out like crazy."

Josh has most recently been linked to singer Rihanna, whilst Kirsten split from Razorlight rocker Johnny Borrell last year.
