Katherine Heigl is Still a Chain Smoker

Chain smoker Katherine Heigl picks up three packs of ‘American Spirit’ cigarettes at a gas station in Los Angeles on Sunday. Despite trying to break the habit, Kat seems like she just can’t let it go!

Her romantic comedy 27 Dresses opened in second-place this weekend, pulling in $22.4 million. Does this make Katherine a bona fide movie star now?

Yesterday, Kat and her momager, Nancy, arrived back in L.A. via LAX airport.

Heigl, 29, and musician husband Josh Kelley, 27, celebrate their one-month wedding anniversary this Wednesday. Congrats to this long-lasting Hollywood couple!
