Beyoncé and Jay-Z Not Expecting a Baby

Fans who can't wait to see Beyoncé Knowles and Jay-Z start a family will have to be patient.

Despite an online report that the singer is pregnant, Beyoncé's rep tells PEOPLE the story is "not true."

In the past, Knowles, 28, has spoken about her desire to start a family with her husband, 40. "I hope that those things will just happen naturally," she told Allure magazine for its February issue.

The pair, who were married in a secret ceremony, celebrate their second anniversary April 4.

The pregnancy rumor surfaced the same week a paternity test confirmed that Knowles's dad, Mathew, 58, is the father of a baby boy, according to a TMZ report.
