Kevin Bacon wasn’t footloose enough.

The Hollywood star tried to chase down a thug who swiped his BlackBerry at a Seventh Avenue subway station Thursday, sources told The Post. The brazen mugger managed to escape and was at large yesterday.

Now the thief is a lot less than six degrees of separation away from a coveted cache of A-list celebrities and boldface names likely programmed into Bacon’s ‘Berry.

The robber boldly swiped the “Footloose” star’s cell at 10:50 a.m. Thursday at the B, D and E station at 53rd Street and Seventh Avenue, sources said.

Bacon didn’t give up the BlackBerry easily. The star took off after the crook, but lost track of him as he raced through the station’s crowd, the sources said.

The numbers for Bacon’s wife, Kyra Sedgwick — who plays a cunning detective on the hit TV drama “The Closer” — is no doubt stored in the phone, possibly along with dozens of other box- office stars who have graced the big screen with Bacon.

But this isn’t the first time Bacon was robbed. He and Sedgwick were swindled by Ponzi-schemer Bernie Madoff, who pleaded guilty to running a $65 billion fraud in March.

NYC Transit officials said no subway personnel were told about the crime, although sources said Bacon did call police.

NYPD officials couldn’t confirm yesterday that a report was filed concerning the robbery.

Often in cellphone robberies the device is simply resold on the street or the crook will use it himself if he has the same wireless service, law-enforcement officials said.

Bacon has long been a cultural touchstone beyond his movie career. He is also famous as the subject of the “Six Degrees of Kevin Bacon” trivia game, in which players try to connect any actor to Bacon through six or fewer common co-stars.

Bacon was traveling yesterday with his band, the Bacon Brothers, and could not be reached for comment, his spokesman said.

The spokesman wouldn’t say whose numbers were in the phone.

Cellphones were the prime target in 37 percent of the 823 robberies committed in the subway system last year, NYPD Transit Bureau records show.
