Don't look directly at them. Model-actress REBECCA ROMIJN-STAMOS, 31, and husband JOHN STAMOS, 40, General Hospital's former resident hunk, are so gorgeous, they may just burn your retinas. So it was perhaps inevitable that the couple would spontaneously combust. After more than five years of marriage, they announced their separation days before the release of her new film, The Punisher. The usual speculation arose that extramarital dalliances were involved. But Romijn-Stamos denied all rumors, saying the only affair she's had recently has been with her new puppy.
