Whovians couldn't believe what they were seeing after Billie's dramatic reveal, which has remained a closely guarded secret. Taking to social media to express their delight, many praised showrunner, Russell T Davies for his 'epic casting decision'.
One said: "OMFG just watched the final episode of . Spoiler alert. Billie Piper as the Doctor. WTF." A second added: "Billie Piper as the 16th Doctor wasn’t what I expected but hey it is something!"
Meanwhile, another declared: "Billie Piper in Doctor Who. In the year 2025. not on my bingo cards."
Another Whovian who was quite clearly overcome with emotion after the episode was Radio 2 star, Rylan Clark. Rylan appeared in Doctor Who two weeks ago, portraying the host of the Interstellar Song Contest, which is akin to a galactic version of the Eurovision Song Contest, on the BBC's iconic show.
Revealing that showrunner Russell had given him a special role on the programme, he said on : "So I have been keeping that secret for a year. I am so excited. I am a massive, massive Whovian.
"I love Doctor Who. I've loved it for years. And when I got that call I was so overwhelmed and I'm not gonna lie, I did have a little tear. Maybe a few more tears. It was the best experience of my life."

Reacting to Billie's reveal in Saturday's show, he told fans he was probably going to 'regret' his emotional post, but shared - with tears streaming down his face - "I'll probably look back at this with real embarrassment, but I've just watched Doctor Who and I don't know what's just happened. Omg, it's unbelievable. What a turn out."
Sharing the heartfelt message, show creator, Russell, replied to the TV presenter, saying: "Love you Rylan" with a big red heart emoji.
Meanwhile, commenting on her return to the show, Billie said: "It's no secret how much I love this show.
"I have always said I would love to return to the Whoniverse as I have some of my best memories there, so to be given the opportunity to step back on that Tardis one more time was just something I couldn't refuse."
