LOS ANGELES—AVN has confirmed that adult performer Amber Rayne, an industry veteran of more than 10 years, has died.

Sources close to Rayne told AVN that she passed away peacefully in her sleep at home either late Saturday night or early Sunday morning, though the exact cause of death will not be known until autopsy reports are completed at the end of next week. She was 31.

Rayne entered the industry in 2005, and racked up close to 500 credits over the course of her career. She was known for both her wild, no-holds-barred sexual performances and her commanding acting chops. In fact, the Detroit native had a background in professional acting before turning to adult, and those skills paid off, earning her immense acclaim and multiple AVN Award nominations, most notably for her supporting roles in 2009's The 8th Day from Adam & Eve Pictures and 2015's Wanted from Adam & Eve and Wicked Pictures. Also in 2009, she was was crowned AVN's Unsung Starlet of the Year.

Wanted director Stormy Daniels, who was one of Rayne's dearest industry comrades, told AVN, "She was a really good friend, and one of the best actresses and performers that I've ever had the pleasure to work with, and I'm just glad that I had the opportunity to work with her and call her a friend."

Daniels added that she will be handling the care of the beloved horse Rayne left behind.
