She's the singing sweetheart who shot to fame on Australian Idol back in 2004.
But when Ricki-Lee Coulter took centre stage at the 2018 Commonwealth Games Opening Ceremony, some fans were left scratching their heads.

Several viewers have taken to Twitter to ask if the 32-year-old musician was actually lip syncing her rendition of Technicolour Love.
"Is Ricki-Lee lip syncing? #GC2018 #OpeningCeremony," one viewer wrote.
"I’m kinda bummed Ricki-Lee is lip syncing #GC2018," another tweeted, as a different fan wrote, "Unsurprisingly, no close ups of Ricki-Lee Coulter’s mouth during the beachside lip synch number".
Be has reached out to Ricki-Lee's representatives for comment.
I'm sure Ricki-Lee was miming that song.— =corym= (@dobondobondobon) April 4, 2018
Meanwhile other viewers have also questioned Christine Anu's performance, and whether that was mimed too.
However a Commonwealth Games media rep told news.com.au that's certainly not the case.
"The Gold Coast 2018 Commonwealth Games Ceremony Team advise that Christine Anu did not lip sync during her performance tonight at the Opening Ceremony of Gold Coast 2018," they told the publication.
"There is no lip syncing and it is live," they added, referring to all performances on the night.
