Kate Gosselin's pricey hairdo costs a whopping $7,000. But her eight kids? $13 a pop!

The reality mom took 6-year-old sextuplets Aaden, Alexis, Collin, Hannah, Joel and Leah to get a trim at Supercuts in Reading, Pennsylvania Friday. Also with her, of course: the Kate Plus 8 camera crew.

Gosselin, 35 -- who visits Angelina Jolie's stylist, Ted Gibson, in NYC once a month for touchups to her own coif -- donned a black mini-skirt and sexy heels for the outing.

Gosselin is obsessed with her looks, sources have told


"She flatirons her hair before going out," said the insider. "She's often looking in the mirror doing her hair and makeup."

Still, she insists she doesn't dote on her strands.

"The honest truth is I care so much less about my hair than everyone in America, obviously," the TLC reality star said in April. "Rarely will I have an opinion or an idea. People care so much."
