The 38-year-old singer revealed during a Wednesday appearance on ITV's Loose Women that she and Castellon had split last summer, after eight years of marriage.

"I am single now," Furtado said. "Someone here needs to update my Wikipedia -- it's not helping my dating life!"

"I went through an emotionally difficult time last summer and I actually wrote and sung myself songs to get through it," she continued. "I was going through a breakup, and I would sing to myself while I drove on these long drives and I thought to myself, 'I'm so lucky that I can write songs because I can soothe myself with them.'"

Furtado, who has a 13-year-old daughter from a previous relationship, said she spent her recent time away from the limelight finding a new balance in life.

"Sometimes you just want to sit home and bake muffins for your daughter, clean my toilet, having a moment to yourself," she confessed. "It's great to have your career take off and have those blessings, but if you don't have that time, when you give and give, you crash."

"I need to stay emotionally and physically well for my daughter," she added.
