And now Lewis has axed reported plans to take her Labyrinth trek around the world - so she can heal with the support of her loved ones.
A source tells Britain's Sunday Mirror, "Leona's heart just wasn't in the tour towards the end of the U.K. leg. She was upset, teary and heartbroken over her split with Lou.
"She'd been with him for 10 years. This was the love of her life. The last thing she wanted was to be on the road away from a support network of friends and family. She wasn't up for it emotionally."
But the star is channelling her emotions into recording new material in the studio: "She's full of ideas. She's got a new lease of life in songwriting. She's putting her heartbreak into her music."
