Despite Leonardo DiCaprio's busy filming schedule (post-Great Gatsby filming, he headed straight to New Orleans for Quentin Tarantino's Django Unchained), he and girlfriend Erin Heatherton seem committed to going the distance.

On Monday, the duo lunched together at NYC's Candela restaurant -- and got caught staring lovingly at one another across the table. Last week, a source tells Us Weekly the pair also stopped by an event at NYC hotspot The Darby, where they were "inseparable all night."

"They showed up hand-in-hand," the eyewitness reveals. "They were acting like a couple all night!"

He's one of Hollywood's most beloved actors. She's a jet-setting supermodel.

But Leonardo DiCaprio and Erin Heatherton played very much the normal couple as they joined each other for a bike ride in New York City yesterday.

The handsome pair clearly revelled in their time together, smiling at each other on the afternoon date and doing their best to go unnoticed.
