Strictly Come Dancing viewers were shocked and surprised by Oscar winner Hayley Mills' cameo on Saturday night's live show.
Fans were in awe of the 73-year-old age-defying beauty as she read out the voting terms and conditions on screen.
Hayley, who won an Oscar at the age of 14, radiated style and grace as she read off the autocue in a chic black trouser suit teamed with white satin shirt after emerging from a sequin curtain.
TV viewers could not believe their eyes as they took to Twitter to share their disbelief at the iconic Hollywood star appearing on the dancing show.
A surprised fan wrote: "I can't believe it, Hayley Mills! What a surprise that was, I [heart emoji] her & she's 73 now! #Strictly."
Another added: "Dear Strictly, how do we vote to keep Hayley Mills in for next week? #Strictly."
Some gushed: "Was great getting to see Hayley mills on strictly come dancing I’ve met her back in 2015," and "Oscar winner Hayley Mills nailing the Ts & Cs!!! #Strictly."
Totally taken off guard, by the star being on the show, others typed: "Hayley Mills on strictly !!!! Oh my goddamn heart #Strictly," and "I tuned in late. Hayley Mills. I'm in bits. I love her so. I can't even.....#Strictly."
"Absolutely loved Hayley Mills growing up great to see her on #Strictly" contributed a pleased fan.
Hayley's TV appearance comes after she shared to The Mirror that her parents did not tell her she won an Oscar.
In 1961 aged just 14, she won a juvenile Oscar – the very last time it was awarded – for Pollyanna, although her parents, actor Sir John Mills and writer Mary Hayley Bell, chose not to tell her at the time.
‘My parents decided not to let me go to the ceremony, because I was very young,’ she explains.
‘It was part of their attitude towards me when I was a child, that I should be kept as unaffected by the world I was now moving in as possible.
'So I went off to school, then when I came back from making a movie in Hollywood, I’d go back to school.’
