He may have received his third Emmy nomination Thursday, but Jeremy Piven isn't the only star in his family.
His 2-year-old niece, Pearl, steals the show in Will Ferrell's video on FunnyorDie.com
, playing his trash-talking, unforgiving landlord.
"Imagine how I feel," says Piven, speaking to PEOPLE from London where he was on the set of Guy Ritchie's film, RocknRolla
. "Suddenly I'm upstaged by my 2-year-old niece who's 19 times funnier than I am and a much better actor. It's overwhelming."
Piven says he hasn't yet heard from his mom to congratulate him on his nomination for playing Ari Gold on Entourage
. "It's not on her radar," he says. "She's worried about taking care of Pearl."
Piven, 41, says he's genuinely impressed by the talent of his sister's daughter. "Pearl is just a comedic crazy kid," he says. "She's so present. Whatever you say, she takes the time to really hear what you say and then repeat it. It's surreal."
