Katie Holmes: Chelsea Jam Session!

Katie Holmes flashes a smile as she jams out to her iPod while out running errands on Thursday afternoon (September 5) in the Chelsea neighborhood of New York City.

The 34-year-old actress has recently teamed up with Bobbi Brown, founder and CCO of Bobbi Brown Cosmetics, to launch a brand-new Bobbi & Katie makeup palette kit, which is set to hit stores this fall.

“It was Katie‘s idea to make one that fits in your hand and quickly fits into your bag,” Bobbi explained to E! News. “The inspiration is chocolate and maybe a little bit of raspberry. They’re really wearable and really pretty.”

FYI: Katie is wearing a Joe’s plaid shirt.
