Milestone Birthday Parties for Demi Lovato at Buddakan, Hayden Panettiere at Koi


No doubt party hats, presents, and novelty cakes were all over NYC’s restaurants this week as they played host to a slew of big celebrity birthday parties. Disney star Demi Lovato marked her 18th with dinner and a party at Buddakan, where guests included family, friends, and ex-boyfriend Joe Jonas. And after a blow-out party in Ann Arbor, Michigan, where she’s currently filming Scream 4, Hayden Panettiere continued her 21st birthday celebrations in Manhattan with friends — a meal at Koi before cocktails at Avenue. For her 23rd, however, Blake Lively kept it casual at Public’s intimate wine bar the Monday Room.
