Audiences at home watching the Coronation Concert were left saying the same thing after watching Nicole Scherzinger's vocal performance in front of the new King and Queen.
The Pussycat Dolls frontwoman sang a rendition of Reflection, accompanied by pianist Lang Lang, which was written and produced for Disney’s 1998 animated film Mulan.
And the singer gave an incredible vocal display wowing the 20,000 crowd at the concert - as well as the millions of others watching at home.
The powerful performance prompted applause from both the King and Queen – with the King turning to the Queen after the performance to say a few words.
Fans on social media agreed and @_xFran tweeted: "Miss Nicole Scherzinger reminding everyone she is a VOCALIST!"
@s_ffron7 agreed and tweeted: "Didn’t know that Nicole Scherzinger could sing like tht, fair play."
@paddysatch1m agreed and said: "Well, who knew Nicole could sing like that!!!!"
@Hobi_kaws tweeted: "I didn't know Nicole has pipes like that." And @soph_rafferty wrote: "Nicole Scherzinger can sing wow"
Speaking ahead of the event Nicole said she felt “overjoyed” and “honoured” to take the stage.
“Now that I’m here, it just feels really surreal. Being on the ground and having Windsor Castle as your backdrop is the dream,” she added.
She had also confirmed that she was going to be breaking new ground and performing the Disney song, prior to her performance.
She said: "I'm actually singing a song I've never sung before, It's called Reflections, from Mulan, the Disney movie and I love the lyrics. I feel like a real life Disney princess up there with the castle in the back. And the song is a beautiful song with the lyrics, so I wanna make sure I communicate those lyrics."
She then added that she will watch the rest of the concert from 'wherever'.
The singer said she found the coronation service on Saturday to be “remarkable”, as her home country of America does not have the same type of pageantry.
Nicole joined the likes of Take That, Lionel Richie and Katy Perry in gracing the Castle's East Lawn for our newly-crowned King and Queen.
