X Factor and West End star Amelia Lily joined Stage School 2017 on E4 for the new series tonight.
Reality series Stage School is back this autumn for a second term, following the lives of the students and teachers at the D&B Academy of Performing Arts.
As well as the familiar faces of the returning students, recent Celebrity Big Brother housemate Amelia made an appearance to give a master class to the school.
She popped up in tonight's show, to help out Jordi and Lucia.
We saw Amelia performing an acoustic cover of her hit You Bring Me Joy before sharing her industry tips with the pair.
Jordi and Lucia then went on to sing themselves, duetting on a cover of Ed Sheeran and Taylor Swift's Everything Has Changed.
Amelia explained: "For me, when I was younger I would have loved to have had someone come and give me advice who knows the industry.
"What better people to take advice from than people who have actually been in the industry and done what you want to do, you know?"
Speaking from the school, Amelia went on: "So on set today it was really fun, I got to watch Jordi and Lucia perform together which was lovely and I got to sing for them and it was really nice because we got to know a little bit more about each other.
"They asked me for advice on being in the music industry and in the theatre industry as well. It was just really nice getting to share bits of information about each other and with them… yeah, it was lovely."
Amelia rose to fame aged just 16 on The X Factor back in 2011.
She then moved into musical theatre, playing the Narrator in Joseph and The Amazing Technicolour Dreamcoat before making her West End debut in Greenday's American Idiot.
As for what she's up to now, Amelia said: "I’ve just done two years of solid theatre, which has been totally different for me, and now I’m back on the gigging scene and doing my music which has been really fun, but obviously I’m still going in for various musicals along the way.
"I like to keep my options open.
"I’ve got panto booked up for at the end of the year already which is really fun… I’m gonna be playing Tinkerbell this year! I found out the other day I get to fly over the audience so I’m pretty excited about that, I’m not gonna lie!"
Stage School 2017 airs Monday-Friday nights at 5:30pm on E4.
