Ella, 18, dominated the summer with her debut single 'Ghost', which shot straight to number one - and now she's hoping to repeat the feat with 'Glow'.
'Glow', which is taken from her debut album Chapter One, is described as a "broody, drum-driven, electronica-tinged track laced with Ella's signature soulful voice".
The second single from the songstress is due for release on 14 September.
"'Glow' will definitely surprise lots of people. It's a sound no one is expecting from me," said Ella.
"The last six months have just been one high after another," she continued. "Performing 'Ghost' in front of 80,000 people at Wembley Stadium is a moment I will never forget."
Ella, who co-wrote all but one song on the album, continued: "My writing's very personal, like an open diary, so the songs had to be raw and honest."
It's been a busy week for Ella, who made her live debut in the US with showcases in New York and Los Angeles.
Ella rose to fame following her X Factor stint in 2012, where she was mentored by Tulisa. Speaking to Reveal in June, Ella told us that Tulisa and show boss SImon Cowell was proud of her success.
"Tulisa's been so supportive of me and it's incredible," she told us. "Simon's been like a rock throughout this and to know that we've come out with a number one, it's amazing. I mean, having your boss proud of you, who could want any more?!"
Chapter One is due for release on Syco Music on 22 September.
