This past weekend, 'twas a full on Kennedy conference out in Hyannisport, with almost all of the ever expanding family in town to celebrate the marriage of Chris Kennedy and Erin Daigle. All except it seems for the Schwarzeneggers and the Schlossbergs (Caroline Kennedy's brood and also the undeniable best, most impressive branch)... Wonder what that's about!

Anyhoo - everyone from the Cuomo sisters to RFK Jr.'s litter was in attendance. Kyra Kennedy, Mariah Cuomo and Kathleen Shriver all matched in purple at the al fresco ceremony. Kick Kennedy daringly sported a silky separates situation composed of a (*gasp*) midriff baring crop top. Conor Kennedy even brought his new girlfriend Ava Dash as his plus one, a sure sign that things must be serious between the two, no?
