The former Gossip Girl star took to social media to post a candid looking selfie.
Two weeks ago she also posted a candid selfie onto her grid page where she was seen looking fresh-faced whilst out and about.
But the actress last posted on her social media profile over the past few weeks, just days before her sudden death.
Michelle rose to fame as a child TV actress, starring as Nona Mecklenberg on the hit Nickelodeon series The Adventures of Pete & Pete.
She captioned the snap: "The warmth before the storm," alongside film roll emoji, a lips emoji and a starry pink heart.
