Let it flow?

After bunching up her $7000 hair extensions in a ponytail last week, Kate Gosselin freed up her pricey new tresses -- beneath a baseball cap, that is -- during a grocery run with her boys.

With five year-old sons Aaden, Collin and Joel at her side, Kate, 34, stepped out on Monday to pick up supplies at a supermarket near their Wernersville, Penn. home.

Bundled up in a puffy black coat, the star -- whose as-yet-untitled TLC reality series is set to premiere later this year --  strutted in signature boot cut jeans and high-heels.

Sources have told that Gosselin "hates" her new hair, which took about 20 hours in the salon to affix.

Meanwhile, her ex-husband Jon Gosselin was spotted partying and making out with his new 25 year-old girlfriend Morgan Christie at the Sundance Film Festival in Park City, Utah earlier last week.
