Andrea, 20, was pictured leaving the X Factor house today (15 October) while wearing a seriously eye-catching Fred Flintstone pullover.
The grey sweatshirt featured a picture of the cartoon character's body, meaning Andrea topped off the head part. And we have to say, the Italian singer does actually look a bit like Fred!
Last weekend, Andrea wowed the X Factor judges and viewers with his first live performance. The hopeful sang a rendition of Michael Jackson's 'Earth Song' and sailed through to this week's show.
In fact, the cheering studio audience liked it so much that they wouldn't let the judges get a word in edgeways!
Former Spice Girl Mel B is Andrea's mentor and the pair appear to be getting on like a house on fire. In fact, Andrea recently revealed that Mel calls him on FaceTime.
He said: "She's so cool. She's calls me on FaceTime and I'm like, 'OMG Scary Spice is calling me'! She's not just a judge she's like a friend."
