HAYDEN PANETTIERE celebrated her 21st birthday all over again on Friday ( 27Aug10) - partying with pals in New York.
The actress reached the milestone on 21 August (10) and marked the occa sion with a spectacular bash on the Detroit,

Michigan set of her new movi e Scream 4 - complete with fireworks and a three-foot dolphin birthday ca ke.
But Panettiere wasn't satisfied with the festivities and jetted back to her native New York this weekend so she could enjoy a more low-key birth day bash with old friends.
The star was spotted feasting on tacos and burritos and downing cheap c ocktails and shots with eight pals at Mexican restaurant Blockheads in Ma nhattan on Friday night.
A fellow diner tells WENN, "It wasn't a very showbizzy gathering and Bl ockheads isn't exactly a celebrity hang-out. But Hayden looked like she w as having a great time. The party was pretty rowdy, with lots of laughing and joking. But nobody minded. She was even treated to a rendition of Ha ppy Birthday by all the waiters, who brought her out some cake. Everyone in the restaurant joined in." There was one conspicuous absentee - Panettiere's giant boxer beau Wlad imir Klitschko. The onlooker adds, "She did look like she was missing her boyfriend. She was on her iPhone every five minutes, checking for messag es from him."
