Giovanni and Marissa Ribisi
Giovanni Ribisi and his twin sister, Marissa, are both famous actors. He's been in films like Gone in 60 Seconds, Saving Private Ryan, and Gangster Squad (and let's not forget his role as Phoebe Buffay's brother on Friends), and Marissa starred in Dazed and Confused, Pleasantville, and Felicity. She launched a fashion line called Whitley Kros in 2007 and is now married to Beck. Fun fact: Giovanni and Marissa were delivered by Bibbe Hansen — who is Beck's mom!
