E! Online – Sean Sasser, of The Real World: San Francisco, died at age 44, his friend and former castmate Judd Winick confirmed Tuesday.

“Our friend Sean Sasser has died. Our love goes out to his family & husband Michael,” Winick tweeted. “We will miss u so much.”

Sasser was introduced to the spotlight in the early ’90s and known for dating Real World star Pedro Zamora. Zamora’s battle with HIV and AIDS brought international attention to a then-taboo topic, which was covered at length on MTV up until his death at age 22.

Sasser, who exchanged rings with Zamora in a televised commitment ceremony, became an AIDS activist leading up to and after his Pedro’s death.
