But Jessica almost messed the whole thing up though – by saying the wrong name.
Don’t worry, she didn’t do a Ross from Friends and say her ex husband Nick Lachey’s name. Instead, she repeated her own name when saying ‘I do’.
Luckily, Jessica managed to shrug it off and the rest of the ceremony was hiccup-free.

Jessica wore a beautiful Carolina Herrera dress in front of her 275 guests. Their one-year-old son was the ring bearer and their daughter Maxwell, 2, was the flower girl.
Ashlee and Jessica’s mum were her joint maids of honour, and her father officiated the ceremony.

Speaking to People magazine about their magical day, the couple said: “We are overwhelmed with complete happiness and love having made our eternal commitment.
“To say ‘I do’ in front of family, friends and most importantly our children has been the happiest moment of our lives.”
Jessica and Eric got engaged on her 30th birthday in 2010, but wedding plans had to put off twice due to her falling pregnant with their children.
