The 25-year-old has featured on a single with dance act La La Land and was in a girl group called Syren.
A video emerged this week, showing Lauren performing an acoustic version of one of the tracks, which was released by Kontor Records and premiered on BBC Radio 1Xtra.
Now Lauren has come under fire ahead of this weekend’s semi-final, after she initially claimed: “I’m so boring. I haven’t done anything.”
According to Now! Online, Lauren has also been telling fibs about her experience on social media.
While she insists her current Twitter account is her first, the publication claims there’s other which describes her as ‘one-fifth’ of Syren.
Lauren is said to have told them: “I only got Twitter a week ago, I know, I’m like some granny… and I just got Facebook.”
She’s one of the favourites to win this year’s competition, but last week Lauren found herself in the bottom two.
After a sensational rendition of Mariah Carey’s Vision of Love, Lauren managed to hold on to her place in the competition while girl band 4th Impact were eliminated.
