Elton John -- Don't Go Takin' My Heart Sunglasses!!! -

The famous sunglasses that became Elton John's signature in the '70s have been mysteriously stolen right out of a famous museum.

A pair of Elton's iconic heart-shaped shades -- which he frequently wore while performing songs like "Saturday Night's Alright," "Daniel," "Philadelphia Freedom," "Crocodile Rock," and "Tiny Dancer" went missing Tuesday from the Rock 'n' Soul Museum in Memphis.

Cops tell TMZ, the manager reported someone opened the locked case which housed the spectacles, but they have no idea how it happened. Museum honchos say someone had to use tools in order to jimmy the lock.

Surveillance cameras did not catch the thief. Cops are now on the hunt for a shady suspect.
