Singer Beyoncé Knowles is reported to be pregnant with her first child calling it a "gift from God", US Weekly magazine reported on Wednesday.
The 29 year old star, who is married to rapper Jay-Z, is said to be "shocked" but pleased at the news.
She had told friends she wanted to start a family but had wanted to complete a world tour and finish her latest album.
News of the pregnancy was revealed by celebrity magazine US Weekly.
A spokesman for Beyoncé has refused to comment on the report. According to the magazine no one was more surprised about the pregnancy than the "Single Ladies" singer herself.
"B was shocked. She loves kids, but she wasn't ready to be a mother just yet," said a source. "She really wanted to get her album done and tour the world again."
Beyoncé is said to be in her first trimester which is less than 14 weeks.
Earlier this year the singer had expressed her desire to start a family saying she "definitely" wants to have children with her husband.
"I hope that those things will just happen naturally," she said of her baby plans.
While there is no official confirmation friends and family have begun offering their congratulations.
Her younger sister Solange Knowles said: "She's got the most beautiful heart. She'll be a great mum."
Record exec Kevin Liles said rapper Jay-Z, who married the singer in 2008, will be a great father. "Jay has been all about family since I met him, and he's always going to be," said Mr Liles.
Texas born Beyoncé is one of the best selling female artists of all time.
She began her career with all girl group "Destiny's Child" before releasing a solo album in 2003 that included one of her biggest hits "Crazy in Love".
While her musical career flourished selling more than 100 million records worldwide she also turned to acting and appeared in the Oscar nominated "Dreamgirls".
After she married Jay-Z in 2008 they were named as the second most powerful couple in showbusiness with a combined fortune of more than $1 billion.
Her financial empire includes a fashion line called the "House of Dereon" and she has lucrative sponsorship deals with Pepsi, L'Oreal and Armani.
She has said one of her proudest moments was attending President Barack Obama's inauguration ball where she performed as the first couple danced to her singing.
Despite her often provocative videos, Beyoncé says she is naturally shy and kept her relationship with Jay-Z a closely guarded secret for six years.
She claims that when she performs she takes on an alter ego known as Sasha Fierce who is able to be more outgoing and overtly sexual than she is in real life.
