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

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, Solange Knowles, and Jay, and amid growing rumors of an impending break-up, said sources close to the superstar couple.

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.

Jay also would be loathe to leave their current posh Tribeca pad, a source said.

Noting that the couple’s 8,309-square-foot Tribeca crib is more than twice the size of the 4,045-square-foot West 19th Street pad Bey was looking at, the source added, “I can say with certainty that Jay is not downsizing.”

The source said it would seem clear the new home is for Beyoncé and their 2-year-old daughter, Blue Ivy.

A publicist for Beyoncé hung up when asked for a comment, while a Jay Z rep said she knew nothing about either of them looking for a new apartment.
