London, Nov 15 (ANI): American R&B singer-songwriter Beyonce Knowles has revealed that she sometimes treats her husband Jay-Z to a visit from her saucy alter ego Sasha Fierce.

Knowles, 27 transforms into Fierce when she puts on her stiletto heels before going on stage.

Asked by talk show queen Oprah Winfrey whether she took her alter ego home to Jay-Z, the Crazy In Love singer said: Sometimes, not often. Only on special occasions.

Beyonce, who married Jay-Z, 38, in April, denied pregnancy rumours.

I want a family but Im not ready yet. Maybe in a couple of years, the Sun quoted her as saying. (ANI)
