The pair - who have two kids Wylda Rae, 23 months and Romy Hero, five months together - tied the knot in Somerset, England on 21.06.12.
Sam, 45, wore a dress by Alexander McQueen`s Sarah Burton while the groom chose Tom Ford for his suit.
The couple met on the set of John Lennon biopic `Nowhere Boy` in 2009 and became engaged the same year.
Aaron has previously defended their relationship against critics who say the 23-year age gap between them is too big.
He said: "I`m in love, I`m blissfully content. No one`s getting hurt. We`re in a loving relationship. We`re engaged. Everyone who matters is happy. Exactly which bit of that do I have to defend?"
Speaking before the birth of Wylda, the actor revealed how he had always wanted to settle down and have a family.
He said: "I`ve always been really up for a baby, I knew very early on - we were very much in love, and it was something that I wanted... It came from me, but maybe it took her to want me to want one. I wanted to be grounded, to surround our kids with love. I love the two girls [Sam`s daughters], I love them to bits, I want the family, and I think that`s what she`s always wanted."
Sam already has daughters Anjelica, 14 and Jessie, five from her marriage to art dealer Jay Jopling - who was once romantically linked with Lily Allen.
