PIX: Why Nick couldn't take his eyes off Priyanka!

Priyanka Chopra and her husband, Nick Jonas, attended the premiere of The Jonas Brothers documentary, Chasing Happiness, in Los Angeles, California.

Directed by John Lloyd Taylor, it chronicles the life of Nick, Joe and Kevin Jonas and is airing on Amazon Prime. 

Priyanka wore a black satin Galia Lahav gown that had a plunging neck and thigh-high slit.

The mesh peeking through the gown added an element of drama to her look.

Nick couldn't hide his smile.

Or take his eyes off her... Aww!

Game Of Thrones star Sophie Turner arrived in a peek-a-boo metallic dress, while hubby Joe Jonas combined a mustard tee with a checked grey suit.
