Tanya Roberts, best known for her roles in the James Bond film A View to a Kill, sitcom That '70s Show and Charlie's Angels, is still alive, her representative informed the BBC.

She was mistakenly announced as having died on Sunday by her agent, Mike Pingel. She remains in a serious condition in hospital in Los Angeles at this current time.

The 65-year-old appeared as geologist Stacey Sutton alongside Sir Roger Moore in his final turn as 007 film in 1985.

She collapsed while walking her dogs on Christmas Eve and was admitted to Los Angeles' Cedars-Sinai Medical Centre.

Mike Pingel told media outlets he mistakenly announced Roberts' death based on information he had received from her partner.

She remains in the ICU in a serious condition. "It does not look good," he told the PA news agency.

The earlier announcement of Roberts' death was met with tributes from fans and former colleagues.

The New Yorker was born Victoria Leigh Blum in 1955, and worked as a model before earning a role in the 1970s horror Forced Entry (also known as The Last Victim).

Roberts' big break came when she replaced Shelly Hack in Charlie's Angels, joining Jaclyn Smith and Cheryl Ladd as third 'Angel' Julie.

Her other credits included the cult films The Beastmaster and Sheena: Queen of the Jungle.

She went on to play Midge Pinciotti in more than 80 episodes of That '70s Show, made between 1998 and 2004.
