CSI actress Lisa Sheridan has been found dead at the age of 44

Very sad news.

CSI actress Lisa Sheridan has died at the age of 44.

The star's death was confirmed by her manager Mitch Clem.

The official cause of death has not yet been revealed.

In a statement, Mitch said:

"We all loved Lisa very much and are devastated by the loss we all feel."

"She passed away Monday morning, at home, in her apartment in New Orleans. We are waiting for a coroners report on cause of death."

Lisa was famously engaged to Sex and the City actor Ron Livingston, who played Berger in the show. Filmmaker Michael Dunaway posted a heartbreaking tribute to his dear friend, after learning of her passing.

"She called me Big Brother, and for all intents and purposes I was. I met Lisa when she was fourteen years old, over thirty years ago. We were immediately attached at the hip, true soulmates from minute one."

"For the rest of the days of her life, she was a central part of mine. She was beautiful, obviously, and an immensely talented actor, and a wonderful friend, but more than anything she really did radiate this impossibly bright energy and life."

"Even in her dark moments. And she had plenty of those, especially over the last few years. I'm trying to take comfort in knowing your struggles and pain and grief are at last, and last behind you."

Our thoughts are with everyone who knew and loved Lisa Sheridan.
