Dunst and Borrell were photographed in Austin last week. Razorlight was in town for the South by Southwest music festival and, while there, Kirsten and Johnny caught some other bands' acts as well. On Thursday, the new couple watched Albert Hammond Jr.'s set. A snitch told E!'s Marc Malkin, "They were hugging and kissing during the performance and at the bar. They looked really cute together." Let's hope Albert didn't notice the new lovebirds. He's Fabrizio's bandmate in the Strokes.

The PDA didn't stop there. The next night, Johnny and Kirsten showed up on a Harley for Kings of Leon's performance. A witness to their romantic antics during the show told the Sun, "They were snogging at the side of the stage. He was wearing an oversized leather jacket and playing air guitar and air drums. She was fluttering her eyelashes at him like a smitten teenager."

Later that night, Dunst and Borrell took in the action at Blender House. On onlooker told Page Six that they were "kissing and cuddling on the dance floor and drinking Absolut cocktails." And as the night continued Kirsten showed her support for Johnny while Razorlight played La Zona Rosa. A witness told Us Weekly, "Kirsten was there rocking out and just got really into him. She and her friend went right to the side of the stage and danced like crazy to every song. She was in a great mood, knew every word and was mesmerized by Johnny. She kept calling things out to him and giggling." Dunst came backstage after Borrell finished his performance and gave him a few congratulatory kisses. Said the spy, "They are definitely together. They were all over each other."
