Wearing the same pink dress that she wore to The Hollywood Reporter's Women in Entertainment breakfast back in December, J.Law didn't realise that all her buttons kept coming undone throughout the day.
Jennifer chatted to Entertainment Tonight about her mishap, of course taking it in her stride.
"Notice my shirt was accidentally undone the whole time. In every wedding photo all of my buttons were undone. It looks like I was like, 'Oh, you thought this was going to be about you?'"
As for what she thought about Amy's incredible wedding?
"It was beautiful. It was very sudden, but it was, I was sobbing the whole [time] — his vows were stunning. It’s when two people really love each other and they really mean it, it shows, and it was a beautiful ceremony and an amazing time. I couldn’t be happier for them."
Congrats to Amy on her special day!
