Tim Gunn and Heidi KlumHow close are Tim Gunn and Heidi Klum? Really close, if you ask the supermodel's husband, Seal.

"When Seal is on the set he refers to me as Heidi's other husband," Gunn tells Parade.

"And the kids are all adorable. Heidi is a wife and a mother first, and her professional career really comes second, which is not to say that you'd ever notice that, but she really is a family person and cares about her family deeply and dearly. How touching is that? I'm the luckiest man in the world," the 'Project Runway' guru adds of Klum.
