Leonardo DiCaprio would fit right in at East Egg.

The actor, who’ll star in the remake of “The Great Gatsby,” paid a cool $1.2 million for a Salvador Dali painting at Christie’s last night, after being outbid on two Picassos, auction-goers said.

“He bid on the Picassos, but it was clear the Dali was what he wanted,” said Rachel Stekson, 23, who works in a Manhattan gallery. “He turned around and was like, ‘Yes!’ ”

DiCaprio’s acquisition, the surrealist “Chevaliers en parade,” depicts a knight and is signed by the artist. The star also owns a Jean-Michel Basquiat.
