The 'Voice' star split from her ex-husband Gavin Rossdale, with whom she shares custody of their children Kingston, nine, Zuma, six, and Apollo, two, in August following 13 years of marriage and, although she's now dating Blake Shelton, she has admitted she's never had much luck with romance.

She said of her love life: "I've always had so many blessings, but also had this unlucky-in-love, tragic thing going on."

And the 46-year-old songstress is convinced her divorce, which was finalised last October, could have "destroyed" her if she hadn't booked time in the studio to work on her music.

She told Stylist magazine: "Last February is when my life fell apart. For six months I didn't know what was going to happen. It was so horrible, I was thinking about the children, and just trying to fix it. And I clearly remember sitting with my girl friend, feeling so embarrassed, and then thinking: I can't go down like this! I'm not going to.

"I've been given this crazy tragedy that I need to turn into music. So I booked some recording sessions. And I still remember waking up that first morning, and I was like, 'F***, why am I doing this to myself? I'm exhausted. And now I need to drag myself to the studio to sing with a bunch of people I don't know and totally embarrass myself!"
