These two Manhattan fat cats have pettiness down to a fine art.

Manhattan billionaire Henry Kravis finally gained custody on Jan. 30 of three abstract Jasper Johns paintings he co-owns with an ex- pal, new court papers say.

Last month, Kravis complained that Donald Bryant had reneged on a deal to alternate possession of the art every year, after they bought them five years ago.

Kravis, worth $4 billion, continues to complain in Manhattan Supreme Court that vineyard owner Bryant won’t go along with Kravis’ desire to eventually donate the paintings to the Museum of Modern Art.
