Kellan Lutz rocked sexy black specs while on the maroon carpet at Nylon magazine's "Guys" party. He's the mag's cover boy!

The Twilight hunk, wearing a killer striped sweater, joined a slew of celebrities at The Beverly in Los Angeles. ... like Jenny McCarthy. We're loving her oh-so-sexy Christian Louboutin boots!


Also at the party ... designers Dylan George, Abbot + Main and Luna Rosa Tequila.
