Pixie will be joining the new series of Strictly, which returns to our screens this Sunday (7 September), and she's been getting in lots of practice.
Taking to Twitter yesterday evening, she said (3 September): "Whaoaoooo just finished our Strictly filming for the day. Now off to sing for @PeaceOneDay #tweetforpeace late!"
Popstar Pixie performed an intimate set at the Hurlingham Club in front of guests including Laura Whitmore, June Sarpong and Anna Williamson.
Performing a selection of her hit songs, Pixie worked the stage wearing denim jeans, a black crop top and a slick of hot pink lipstick.
The outfit was casual in comparison to Pixie's sparkly yellow frock that she sported at the official launch night on Tuesday (2 September).
In the Strictly Come Dancing red carpet show, which premiered yesterday exclusively on BBC iPlayer and the red button - Pixie told host Zoe Ball: "I don't ever like to put on too much pressure because I think that's where it all goes wrong. When I was thinking of going into it, I was like, 'Let's have fun and enjoy it and have a life experience'.
"I'm excited to learn the Latin numbers. I think they'll be the most fun - tricky but fun," she continued. "I actually think that ballroom will be the hardest because of the posture that they do."
Strictly Come Dancing will launch on Sunday (7 September) at 8pm on BBC One.
