Singer Alison Goldfrapp has refused to label her sexuality, saying she is happy to swing both ways.

The Goldfrapp performer was outed two months ago by a Sunday newspaper, which mentioned her in a feature about “mid-life lesbians” and carried an image of her with partner Lisa Gunning.

Speaking to the Times, Goldfrapp said the story was “a bit of a shocker” because she didn’t know she and Gunning, a film editor, would be mentioned in advance.

She said: “A friend texted me: ‘Oh, there’s a really nice picture of you and Lisa in this magazine.’ I was like: ‘What picture? Where? Really? Hold on a minute . . .’”

Goldfrapp added: “I don’t know why people would find it surprising. Everything we’ve ever done – the music, the looks, the shows – has all been quite ambiguous and undefinable, and that’s how I am.

“I don’t like to be defined by my sexuality, which swings wherever I like to swing. I’ve had lovely, long relationships with men as well. I just happen to be in a relationship with a lady at the moment.

“I don’t like to be pigeonholed in my life or my music either. The best policy seems to be to go with what feels right, so I do.”
