Why do celebrity-wedding vows require so many tune-ups? Megan Fox and Brian Austin Green are apparently following in the "I do" retread footsteps of Mariah Carey and Nick Cannon, Heidi Klum and Seal, Jennifer Lopez and Marc Anthony, Tori Spelling and Dean McDermott, Ice-T and Coco and the rest of their pledge-happy ilk. E! News says the lovebirds, who quietly tied the knot on a beach in Hawaii last year, will likely mark their first anniversary by reaffirming their commitment to stick together until death. Megan, who's in town to receive an award at the Maui Film Festival (it's for a documentary she did, not that "terrible" movie with Mickey Rourke), reveals the vow redo is her hubby's idea. "I didn't think that I was into it until my relationship with Brian," Fox fesses up to E!. "He's very sensitive and very emotional. He's a Cancer, so he's very all about feelings and relationships and he cries about everything. He'll want to do it, so I'll do it for him."
