Beyonce and Jay-Z Fight Over Children

Beyonce's marriage to Jay-Z is already under strain -- due to the couple's conflicting views about having children, MediaTakeOut reports.

"Jay Z is ready to have children. He [and Beyonce] dated for years, now they're married ... and for him - it's time for children," a source close to the 99 Problems rapper tells the website.

The couple married in a secret ceremony in NYC on April 4.

Knowles, 26, is prepared to have a baby -- but wants to wait at least another 2 years. "Beyonce is very career focused. She has another album due this year and a couple of major film projects in the works," the source says. "Her career is moving at 90 miles per hour and she's not trying to have it slowed down by a baby.

"[Jay Z and Beyonce] are best friends so it's not like they're fighting over it ... but they both feel very strongly about [their positions] - if one of them doesn't relent, I think it could be a big problem."
