Tanya Roberts, best known for her stint as a Bond girl in A View To A Kill, has died unexpectedly at the age of 65.

The actress - also known for That '70s Show and Charlie's Angels - is said to have collapsed on Christmas Eve after taking her dogs for a walk.

According to TMZ, Roberts was then taken to hospital and put on a ventilator but never recovered and died on Sunday.

Mike Pingel, Roberts's long-time representative and good friend, told The Hollywood Reporter: "I'm devastated. She was brilliant and beautiful and I feel like a light has been taken away.

"To say she was an angel would be at the top of the list. She was the sweetest person you'd ever meet and had a huge heart.

"She loved her fans, and I don't think she realised how much she meant to them."

Fellow Bond girl Britt Ekland paid tribute on Twitter, writing: "Rip Tanya Roberts, once a Bond Girl always a Bond Girl!"

Roberts is survived by her husband Lance.
