Days before being rushed to the hospital for substance abuse, Demi Moore was partying like a rock star at Miley Cyrus' boyfriend's birthday bash at Club Icon in L.A. You know, the party with the infamous penis cake

Apparently, the 49-year-old actress played the role of "cool mom" and tagged along with 23-year old daughter Rumer Willis and her friends in the VIP section. However, Demi couldn't keep up with the younger crowd, leaving shortly after midnight.

Although hindsight is 20/20, you can't say you didn't see her meltdown coming.
