Alec Baldwin was scratched from hosting amfAR’s Cannes gala last night when a tiff with Harvey Weinstein boiled over. But the two buried the hatchet afterward. Baldwin reportedly bad-mouthed Weinstein when the mogul declined to appear in a documentary. Then it was tit-for-tat before the amfAR fete, with some saying Baldwin was banned and others that he walked. But cooler heads prevailed: Baldwin came as a guest and wrote a note: “HW, my apology to you and congratulations on a successful event.” Harvey said in a statement: “Alec couldn’t have been more gracious. We all lose our tempers sometime; trust me I have, too. We all appreciated his generosity to everyone at amfAR.”
