Pixie answered pupil's questions and sang acoustic versions of her songs
Triple Brit Award nominee Pixie Lott visited a local school in Brentwood to inspire pupils to take up music.
The 'Mama Do' starlet spent several hours at Brentwood County High School, which is close to her home.
As part of the government's 'Tune in -Year of Music' campaign, she sang live, answered pupil's questions and helped inspire their music lessons.
She said: "It's wicked, it's so cool to come to a local school and perform to a young audience, it was a lot of fun."
The 19-year-old hit number one in 2009 with 'Mama Do' and has been nominated for British Single, British Female Solo Artist and Best British Breakthrough Act in the 2010 Brit Awards.
Although she was born in Kent, she moved to Essex in her early teens.
She told BBC Essex's Ian Wyatt it was not impossible for anyone in the assembly to follow in her footsteps.
"You definitely can, if you just keep trying and you're passionate and determined enough about music. If you keep trying you can definitely get there I think," she said.
Head teacher at Brentwood County High, Carol Mason, was delighted to have Pixie in her assembly to emphasise the importance of music as a subject.
"It's absolutely wonderful, the kids and staff have absolutely enjoyed it - thrilled," she said.
"Who knows, we could have the next Pixie Lott in our school. Without cherishing that early on, we'll never know."

For one pupil, Michael, there were a number of reasons to be cheerful by Pixie's arrival.
"She's amazing, she's the best live thing I've ever heard," he said.
"I got to miss a really boring lesson, so it was great."
