Kat Von D spotted with former boyfriends?

Kat Von D was spotted in the company of two alleged former boyfriends, it has been reported.

According to an eyewitness, Von D - who was believed to be dating Jesse James - was seen at a Slash concert at the House of Blues on October 5 with her ex-boyfriend Nikki Sixx.

"They were on the balcony chatting and ended up disappearing together," a source told People. "They were acting pretty cosy and chummy."

Von D was also apparently seen at dinner with supposed past love interest Bam Margera.

"They were being very sweet to each other," an eyewitness noted. "They didn't hang around for long, and after a quick cigarette break, they made a dash for the exit."

James and Von D were last seen having lunch together on October 3.
