Kimberley Jane is Portsmouth’s new lip-sync sensation - but the technique has caught out more than a few stars over the years.
Kimberley made no secret of the fact that she was miming in an impromptu performance of the Frozen hit Let It Go as the song was played on loudspeakers in the city centre.
Video of her enthusiastic performance was seen thousands of times on the internet.
But lip syncing can have its pitfalls, as these stars - among others - have found out.
Bieber’s 2011 appearance on the US programme The Today Show featured his version of the classic festive song Santa Claus Is Coming To Town. It started well enough but he hit snags in the second part of the song.
In 2004, Ashlee Simpson was booked to sing two songs - Pieces of Me and Autobiography - on Saturday Night Live. She appeared to start singing Autobiography only for the lyrics of Pieces of You to boom out instead.
Aguilera was chosen to sing the US National Anthem at the Super Bowl in 2011 - but failed to deliver the line “O’er the ramparts we watched.” She said later that she was so caught up in the spirit of the song that she lost her place.
Miley Cyrus appeared on Saturday Night Takeaway in 2009 but got 17 seconds into Fly On the Wall before lips and sound appeared to part company.
It goes to show that sometimes things can turn full circle. Mariah Carey’s performance on the American Idol finale last year was so good that in some quarters it was suggested she must have lip-synched the entire thing.
But the star later insisted she sang every song live during her greatest hits medley.
