Less than a year after joining the cast in the iconic role of villainous Alexis Carrington, Nicollette Sheridan will be exiting “Dynasty”.

TVLine first reported that the former “Desperate Housewives” star would be leaving the show after joining the cast partway through the first season.

“Nicollette Sheridan will be leaving ‘Dynasty’ in order to focus on some personal family responsibilities,” read a statement from The CW and CBS Television Studios. “She was a valuable asset to the show and we wish her continued success in the future.”

Sheridan then said in a further statement obtained by ET Canada: “Working on the ‘Dynasty’ reboot and reprising the iconic role of Alexis has been thoroughly enjoyable, but the chance to spend precious time with my terminally ill mother is more important to me right now.

“I am profoundly grateful to Mark Pedowitz (The CW) and David Stapf (CBS) for graciously allowing me to return to Los Angeles to be with her, and I wish them and everyone associated with the show nothing but continued success. I am hopeful that my fans will embrace my successor with as much passion as they embraced me.”

According to TVLine, Sheridan’s final appearance in the role will air in March, while an insider indicated the role (originally played by Joan Collins in the 1980s primetime soap on which The CW’s reboot is based) may be recast.

The publication also noted that Sheridan’s departure is “the third major cast shake-up to rock the reboot in less than a year,” following the exits of series regulars Nathalie Kelley and James Mackay.
