Angarano bonded with Stewart on the set of 2004 movie Speak and now he has fallen for another co-star, according to Us Weekly magazine.

The new couple went public with their affections for each other at the 2013 Sundance Film Festival in Utah last week (21Jan13) when Angarano held his rumoured girlfriend's hand on the red carpet at the premiere of her new film Afternoon Delight.

A source tells the publication, ""They try keep it pretty quiet but (they're) very supportive of each other. She's blowing up and she loves having him around to help take away some of the stress of it all.""
