Actors William H. Macy and Felicity Huffman are another of Hollywood’s most famous couples that has over a dozen year age gap between them. Surprisingly, Macy tried to woo the Desperate Housewives‘ actress for years before realizing he was her one and only.

“Bill Macy asked me to marry him several times over several years. And I was finally smart enough to go: ‘I’m going to marry this guy or really lose him for good.’ And it was after we broke up for four or five years when he asked me again, I knew I couldn’t say no,” Huffman said in an interview back in 2013.
