Sam Taylor-Johnson and her husband Aaron Taylor-Johnson may just be proof that all you really need is love. 

Because 16 years into a romance that began when Sam, 57, directed Aaron, 33, in his role as Beatles legendJohn Lennon in 2009's Nowhere Boy they have all they need. They've got their daughters—Angelica, 26, and Jessie, 18, from Sam's 11-year marriage to art dealer Jay Jopling and Wylda, 13, and Romy, 12, the girls they welcomed ahead of their 2012 vows. "Four very strong, opinionated young women," as Sam recently described them to The Hollywood Reporter.
