She also has been performing new versions of her hit songs in her Metropolis Sessions on YouTube, saving fan favourite Naked until last.
The Strictly Come Dancing star said: “Here’s the one that you have all been waiting for… Naked.
“Revisiting all these songs was such an emotional journey for me.
“I was thinking, ‘How the hell do we make this one work?'”
Naked was released 21 years ago in 1996 and reached number three in the charts for the singer.
Louise is going on a tour next year, beginning with a performance at Under the Bridge in London.
What a scorcher!
On Twitter she expressed her excitement about getting back on the stage as she wrote: “Only 3 weeks to go before my first live show in 15 years !!! At @UTBlondon who’s coming down?”
Her Twitter followers responds in their droves to express their excitement over her musical comeback.
One person said: “Me! Cannot wait! 15 years is a long ol time! Can’t wait to see you on stage singing your songs.”
Another said: “That voice. Still got it and sounding more authentic than ever, Lou. Everything’s gonna be fine.”
A third person wrote: “See you there Louise. You are going to smash it! Can’t wait.”
It comes after Louise reportedly filed for divorce from her husband of 19 years, Jamie.
A source told The Sun: “They have come to a mutual agreement that divorce is the only option. Louise has filed the paperwork and there’s no going back.”
