Beyonce and Jay-Z's baby 'due in February 2012'

Beyonce showed off her baby bump after performing Love On Top

Beyonce has revealed that she is due to give birth to her first child in February 2012.

Australia's Channel 7 Sunday Night show confirmed the date during an interview with the US singer.

This will be the first child for 29-year-old Beyonce and her husband of three years Jay-Z, who is 41.

She announced the news at the MTV VMA awards in Los Angeles in August, where it broke a Twitter record with fans reacting to the news.

Users on the microblogging site posted 8,868 tweets per second when the singer showed off her baby bump after her performance at the event.

The previous record was 7,196 after Japan's win over the US in the women's World Cup final in July.

"It's crazy, I don't even Tweet," she said during the interview.

On being pregnant she added: "It already has changed my life. My husband and I have been together for 10 years. I feel like it's time."

It means the baby was conceived before her high profile UK performances at Glastonbury and T In The Park this summer.
