Sometimes, worlds collide in a positive way.

This penthouse duplex at the Chelsea Mercantile — the building where Katie Holmes resides — has plenty of good celebrity vibes. The unit is owned by hockey star Scott Gomez and has been rented to a top fashion designer, Marc Jacobs, and a pop star, Nick Jonas.

Now that Gomez is a free agent — attending the New Jersey Devils’ training camp for the 2014-15 season on an unsigned, try-out basis — he’s putting the three-bedroom, three-bathroom, 2,062-square-foot condo on the market as a $23,000-a-month rental.

It’s currently set up as a two-bedroom with a den and lots of entertaining space, with high ceilings, blackout privacy shades and a huge terrace.

Corcoran’s Noble Black and Erik Ternon have the listing.
