Those Beyoncé baby rumors may have just gotten a big boost – from the lady herself. An earwitness says he heard the superstar confirm with her own words that she is expecting Jay-Z’s baby.
The confession allegedly was made in a private room at the opening of Jay’s 40/40 club in Atlantic City on Wednesday night.

However, the admission would jar with a report from another guest, who told me: “I definitely saw her drinking Champagne,” implying that she was unlikely to be pregnant. The gala opening drew pals of the couple, including Destiny’s Children Michelle Williams and Kelly Rowland, Serena Williams, Diddy, Magic Johnson and Barry Bonds.

Speculation has risen in the past few weeks, with some observers saying they can spot a telltale bump. Another source, who attended a lunch party with the singer almost a month ago, told me the table talk was all about her presumed pregnancy.

And the official word on Beyoncé’s “confession”? A concise: “This is not true.”
