Singer/songwriter Sophie B. Hawkins is pregnant with her second child, at the age of 50.

The Damn I Wish I Was Your Lover hitmaker conceived using a sperm donor and her own frozen embryo, and admits she wanted to expand her family for the sake of Dashiell, her six-year-old son with her former domestic partner Gigi Gaston.

Hawkins tells, she says, "I found Dashiell really needs a sibling... My son has one parent who's 50. I want him to have a family of young people too!"

However, the star reveals she initially worried she could be too old to have another child, adding, "I went through waking up crying and saying, 'Am I too old? Will I suddenly at 51 have my knees give out?' Now I don't have any of those fears because I feel healthy and strong. I'm also setting up a good net of support, and that's the key to anybody having a child... For me, the main decision was emotional. I've been wanting to have a child since Dashiell was 1, but I was working too much and there was a lot going on in my relationship."

Hawkins entered a domestic partnership with her manager Gaston in 2008, but they filed to end the union last year (14).
