Leonardo DiCaprio spotted kissing model Kelly Rohrbach

NEW YORK, June 11 (UPI) -- Leonardo DiCaprio cozied up to Kelly Rohrbach this week in New York.

The 40-year-old actor and 25-year-old model were spotted kissing on the West Side Highway bike path before meeting DiCaprio's mom, Irmelin Indenbirkin, for lunch.

Onlookers told Yahoo! Celebrity the pair enjoyed mint mojitos, lobster flatbread and chicken lollipops with Indenbirkin and her friend. DiCaprio and Rohrbach were forced to disassemble their bikes after the actor's driver showed up to take them home.

"Leo and Kelly are just hanging out at this time," an insider told E! News of the rumored new couple. "Nothing serious. They are having fun and enjoying the summer. Kelly and Leo are not exclusive yet."

DiCaprio and Rohrbach were first linked in April, and were spotted together again earlier this month. The actor is well known for his many relationships with models, including Gisele Bundchen, Bar Refaeli and Toni Garrn, whom he split from in Dec. 2014.

DiCaprio will next appear with Tom Hardy and Domhnall Gleeson in revenge thriller The Revenant. Rohrbach is known for her modeling work with Sports Illustrated, and has appeared on Two and Half Men, The P.E.T. Squad Files and Rizzoli & Isles.
