Macaulay Culkin's actor brother Kieran Culkin has found love on the set of his new movie Paper Man - with co-star Emma Stone.

The pair hit it off after they met while working on the comedy drama, which also stars Ryan Reynolds and Lisa Kudrow.

And according to the New York Post's PageSix column, Culkin and Stone have been enjoying more and more time together off-set - with one source telling the publication they have been frequenting the Backyard Bar in the Montauk area of the Big Apple, where the movie is being filmed, "almost every night".

The insider adds, "They seem to get along well and have spent time there, just the two of them... closing down the bar in the wee hours of the morning."
