KEY POINTS:
Kirsten Dunst is allegedly dating Razorlight singer Johnny Borrell.
The Spider-Man 3 actress and the rocker were seen canoodling at Texas music festival SXSW.
A source said: "They were kissing by the stage. She was fluttering her eyelashes at him like a smitten teenager."
Dunst, 24, and Borrell, 26, met last week in Los Angeles when the actress went to watch Razorlight perform (see photo on People.com).
Sources say they are an item, even though Borrell has a long-term girlfriend back home in Britain.
