THE MASKED Singer viewers are convinced a 90s megastar is hiding behind the Eiffel Tower costume.
The architectural wonder, which in real-life is in Paris, belted out swoon-worthy hit Angels by Robbie Williams on Saturday night.
Now fans think the star's "scratchy" voice belongs to none other than British singer and musician Sonique, 58.
The pop star shot to fame a member of dance band S'Express during the early 90s, but achieved greater success as a solo artist with hits like It Feels So Good, I Put a Spell on You and Can't Make Up My Mind.
She also won the 2001 BRIT Award for British female solo artist.

One convinced viewer wrote: "I think Eiffel Tower is Sonique. Just putting that out there as not heard anyone say it but I've been thinking it since they first sang."
"This series is HARD. I still think Eiffel Tower might be Sonique and Air Fryer could be Kym Mazelle. Not a clue really on Owl," a second said.
A third simply guessed: "Sonique has to be Eiffel Tower."
Viewers have also recognised the voice as popular pop star Anastacia, 55.
Many thought the American singer-songewriter's voice fit the bill perfectly.
One wrote: "Reckon Eiffel Tower is Anastasia."
A second agreed and said: "Eiffel Tower sounds like Anastacia to me."
A second shared: "I said the same as Mo and thought Eiffel Tower sounded so like Gabrielle. The only other person that sounds like that to me is Anastacia."
Meanwhile, the character has left a series of clues.
A post from The Masked Singer's official Instagram page featured the character and the words: "Ooh la la, ooh, la la, mon chant etait tres bon [my song was very good], it may not have been Monty but it was def Python."
