We don't think Mila Kunis could ever look bad, but the hottie seemed embarrassed that she didn't have a stitch of makeup on while leaving a coffee shop in LA on Sunday.

The Black Swan actress braved the June gloom to get her java fix, and she looked so chic in her oversized Chanel bag, cream sweater and skinny jeans. We have no idea why she'd want to hide.

Kunis was honored with Spike TV's Guy's Choice "Holy Grail Of Hot" award last weekend (Jen Aniston won "Decade of Hot"), and we definitely agree with the guys!
