Cassandra Lynn Hensley, a Playboy centerfold who was named Miss February in 2006, was found dad yesterday at a friend house in Los Angeles. She was 34 years old.

Officials tell TMZ that the friend found Hensley's corpse floating in a bathtub and called the police immediately.

When paramedics arrived, they could not revive Hensley, who is believed to have died from an overdose. Foul play is not suspected at this time.

Hensley was a frequent Twitter user and her last Tweet, from three days ago, reads especially eerie in light of this tragic development:

"Unspoken obligations prevent you from doing what you wish today ... No matter what you do now, you might not feel completely fulfilled. Working harder isn't the answer, but neither is escape."

We send our condolences to her friends and family members.
