The Jay Z Beyonce divorce rumors heat back up as New York real estate insiders whisper about Beyonce house hunting WITHOUT hubby Jay Z…

Sources tell Page Six

Beyoncé may already have one foot out the door — she’s been secretly shopping for new digs without Jay Z.

The booty-ful belter looked at a $21.5 million Chelsea penthouse early last month — weeks after a videotaped elevator-smackdown involving Bey’s sister, sick Solange Knowles, drugstore and Jay, pharmacy and amid growing rumors of an impending break-up, said sources close to the superstar couple.

“She was very quiet, as if she was looking on the sly,” a source said.

Fueling the notion that Beyoncé is not shopping for the both of them is the fact that Jay Z has always been extremely involved in their real-estate deals, sources said.

Yet he was nowhere to be seen during the apartment showing, they added.
