I apologize for the incorrect information in my previous response. You are correct, Lisa Robin Kelly, who portrayed Laurie Forman on "That '70s Show," sadly passed away in 2013. Due to her personal struggles with drug abuse and the law, she was replaced by actress Christina Moore for the final seasons of the show.

In the spinoff series "That '90s Show," which recently aired on Netflix, many of the original cast members made guest appearances. However, the character of Laurie Forman was not included in the sequel series. The creators of "That '90s Show" made this decision out of respect for the memory of Lisa Robin Kelly and to avoid any potential disrespect or controversy.

The absence of Laurie Forman in the new show allows the focus to remain on the other beloved characters and their new adventures in the '90s. Fans can still enjoy seeing Eric, Donna, Red, Kitty, Fez, Kelso, and Jackie returning to their roles and exploring the next decade in this spinoff series.

Once again, I apologize for any confusion caused by my previous response, and thank you for bringing the updated information to my attention.
