Cocky playboy Jeremy Piven got burned again recently when Heroes star Hayden Panettiere shot down his lecherous advances.

Star magazine reports: "Jeremy chatted up Heroes hottie Hayden Panettiere - who, at 19, is 24 years younger than Jeremy. 'He was trying to be charming and kept saying he ”˜wanted to show her around town,'" says a partygoer. 'But Hayden soon excused herself and escaped.'"

See guys? Even when you're on a hit TV show, chicks will still blow you off. Or perhaps Panettiere wants to eat at Nobu - and with Piven as her date - well, no spicy tuna for you.
