Casual customer! Leonardo DiCaprio looks trim in form-fitting blue T-shirt as he steps out solo in New York

He's been single since splitting from Nina Agdal in May. 

And Leonardo DiCaprio once again cut a lonely figure as he walked solo through East Village in NYC on Friday. 

The 42-year-old actor was spotted with his ear buds in while out for a stroll.

His form-fitting blue T-shirt revealed not only the chilly weather, but the outline of a strange circular object just underneath his collarbone. 

It's not clear what it was, but the Oscar-winner appeared to try to shield the object from photos using his closed umbrella. 

He also seemed to be carrying a hefty item in his jeans pocket, despite having his phone apparently in his hand.

A camouflage baseball cap covered his head and, along with dark glasses over his eyes, gave little help disguising the distinctive Wolf of Wall Street actor. 

It was also announced on Friday that Leo is teaming up once again with Martin Scorsese. 

They are developing a film adaptation of true-crime thriller Killers of the Flower Moon: The Osage Murders and the Birth of the FBI, according to Variety

The project is based on the bestselling book by David Grann, a staff writer for the New Yorker and author of The Lost City of Z. 

The actor split with his 25-year-old Sports Illustrated model girlfriend back in May, and whilst he's been surrounded by beautiful women since, he doesn't appear to have ventured off the single-guy path just yet. 

Leonardo's longest relationship has been with Gisele Bundchen, who is now wed to Tom Brady.

He has also dated Bar Refaeli, Erin Heatherton, Blake Lively and Toni Garrn, among others.

He is also currently producing Robin Hood, starring Jamie Foxx, and due for release in 2018.
