BFFs Katherine Heigl and Sarah Chalke Age Over 30 Years in New Firefly Lane Teaser

We saw the first teaser for Firefly Lane months ago, but now we've got another look at the upcoming series based on Kristin Hannah novel's about two lifelong friends (Katherine Heigl, Sarah Chalke) and how their relationship endures through tumultuous life events over three decades.

We never realized much we needed to see Chalke with feathered '70s hair until right now.

Firefly Lane premieres February 3 on Netflix.

Andy Hunsaker has a head full of sitcom gags and nerd-genre lore, and can be followed @AndyHunsaker if you're into that sort of thing.
