Kris Jenner -- Minnie Cry For Attention

Kris Jenner celebrated her 59th birthday by donning a Minnie Mouse onesie at Disneyland -- but the real question ... doesn't Kris Jenner get enough attention?

Kris hit up the Happiest Place on Earth Wednesday with her grandkids and Kourtney Kardashian ... and the reality star was wearing an outfit typically worn by pre-teens.

It's safe to say ... everyone in the park knew Kris was there, and it wasn't hard to find her.

She looks good ... but certain parts, well, there ain't nothin' mini.
