Although Klum went public with the relationship -- her first since she and husband Seal announced their separation in early 2012 -- in September, Williams argued to her audience that Klum and Kirsten have been romantically involved for much longer than that.
"He's worked for Heidi in the family for four years. Seal, you know what that means -- and not just when you were out of town," she said, later adding, "I don't think this is a new relationship, do you?"
(Of her South African-born beau, Klum recently told German magazine Bunte "I'm in love!" She explained to Katie Couric back in September that the romance had "just started" with Kirsten over the summer. Although Seal initially lashed out about Klum's new beau, complaining that his ex was "fornicating with the help," he later explained that he never implied his wife cheated during their seven-year marriage.)
