TMZ camera's caught Sean Stewart and his father Rod last night at Koi in Los Angeles. Oh yeah, Sean's smokin' hot stepblonde, Penny Lancaster, was there too. Who says boys night out can't have a little estrogen in the mix?

When asked about Kiefer's DUI and Britney's bodyguard -- Sean and Rod stayed tight lipped. Like father, like son.
