Sundance 2011: Jeremy Piven, Rob Lowe look like twinsies

How cute. From their full heads of hair, to the un-botoxed foreheads and stubbly faces -- Not to mention those scarves -- Co-stars Jeremy Piven and Rob Lowe look like a match made in middle-aged-heaven.

The duo is living it up in Park City, UT for the premiere of their film, "I Melt with You," at the Sundance film festival.

Lowe also got a little bro-mantic at the films press junket. He wound up on the receiving end of a smooch from director, Mark Pellington.

The thriller also stars fellow HBO stars Thomas Jane and wait for it... Sasha Grey.
