. The former Victoria's Secret model - who announced her separation from Orlando Bloom
after three years of marriage this fall - is rumored to be dating Aussie billionaire James Packer. Packer, 46, is a casino mogul and an insider tells People he and Kerr, 30, "are definitely seeing each other." (Though a Kerr source says the two are strictly friends.) In September, Packer announced that he had separated from his wife, Erica Baxter. The two were married in 2007 in a lavish ceremony on the French Riviera.
