Talk about a cold cookie: ASHTON KUTCHER squeeze MILA KUNIS got icy stares when she coldly blew off a cute 12-year-old female fan who approached her at a skating rink in the San Fernando Valley as the actress stopped to take a break while chatting with three pals.

Said My SpyWitness: “The little girl gushed that she was a HUGE fan and just loved Mila’s movies. But Mila just stared with frosty eyes when the girl asked if she could take a photo with her. Without even giving her so much as a brief smile or thank you, Mila literally turned her back on the kid, whispered something to her friend and skated off.

"Then the friend told the girl, ‘Mila doesn’t want to be bothered, so don’t approach her, or speak to her, again.’ The kid turned beet red and began to tear up as she watched Mila skating around laughing with her friends!”

(What a nasty…Kunis!)
