Boys will be boys! Leonardo DiCaprio giggles while being chased by Lukas Haas as they hail a taxi in New York

They have been friends since the Nineties.

And it seems like Leonardo DiCaprio and Lukas Haas still haven't grown out of their boyhood playfulness.

The 42-year-old Oscar-winner and 41-year-old fellow thespian were spotted gallivanting around New York City together on Thursday.

At one point Lukas even chased a giggling Leo as they hopped into a taxi together.

The two men seemed to be having some good old fashioned fun as they shared a few laughs together while hanging out in the Big Apple.

Leo was dressed comfortably as always in a pair of grey shorts with a white T-shirt.

He completed the casual cool look with navy blue loafers and a blue Los Angeles Dodgers baseball cap.

Lukas wore a plain shirt, grey jeans, beat up boots, a fedora and sunglasses.

The outing with his best pal comes after being seen frolicking the beach in Malibu with model Elizabeth Turner earlier this week.

Leo seems very familiar with the stunner as just weeks before they were seen boating off the coast of France together alongside Tobey Maguire and a host of other beauties.

A Duke University grad, Elizabeth started her modelling career shooting for Seventeen magazine and Teen Vogue while in high school, according to GQ.

She's since worked for Guess and cosmetics company Too Faced.

Though the blossoming model says she does hope to return to her studies one day.

Asked what she would be doing if modelling wasn't her current job, she told the magazine: 'I would be in grad school pursuing a Ph.D. in psychology. I would like to go back to school one day.' 

Leonardo, meanwhile, has made headlines for his recent and generous $1 million donation to help victims of Hurricane Harvey.
