Beyonce 'worried about baby secret'
Beyonce has revealed how tough it was for her to keep her early weeks of pregnancy under wraps.
The singing superstar, who is expecting her first child with husband Jay-Z, wanted to break the news to the world when she was ready, but feared her secret may have been obvious to her fans.
"The whole time I definitely was thinking, 'everyone knows, everyone can see'," said the singer before the screening of her new concert DVD Sunday in New York.
It became particularly difficult for her to hide the growing baby bump when the Grammy-winner performed for four nights to sold-out crowds at New York's Roseland Theatre in August.
"When you're pregnant, it's a little bit harder to breathe, so it was hard doing all the choreography and singing at the same time," said the 30-year-old singer in an onstage interview.
US fans who didn't get a chance to catch The Intimate Nights shows - which Beyonce said was her last concert performances of the year - can get a behind-the-scenes look in her new Live at Roseland DVD, available exclusively at Walmart this week.
Along with classics from her Destiny's Child days and major hits from her solo career, the DVD includes interviews with the singer, home footage of rehearsals and special family moments - even shots of Beyonce in a wedding gown.
She's also hoping the film will serve as a time capsule for her unborn child, a chance for him or her to say, "I can't believe I was in that belly", she said.
