We're used to seeing Leonardo DiCaprio kissing on young models or actresses like Blake Lively -- but his latest liplock is with a woman almost 30 years his senior!

The actor was spotted on the set of his latest movie, "The Wolf of Wall Street," on Tuesday afternoon in New York.

Leo, 38, was seen making the moves on 66-year-old "Absolutely Fabulous" star Joanna Lumley while filming ... laying a wet one on her in the middle of Prospect Park, Brooklyn.

In the Martin Scorsese movie, DiCaprio plays a stockbroker who refuses to cooperate in a large securities fraud case involving corruption on Wall Street.
