Did Kris from the Kardashians REALLY change her name from Jenner back to Kardashian?

(If so, that's Sooo Stupid, she represents her younger daughter, whose last name is Jenner & her Other daughter's last name is Odom & Even Kim's getting married name so she's Probably changing Her last name Too!) Also, the way Kris referred to her daughters as a "product" & a "brand"? They:re Not a "brand" & they're Not a "product," they're her Daughters, they're People!
