The 'Leftovers' star has revealed the TV host, 47, was so overcome with emotion when he performed the nuptials for the couple that a few tears rolled down his cheek.
Speaking on 'Good Morning America' on Wednesday (30.09.15), Justin said of his pal's performance: ''It was exactly what you would want him to do. He was extremely funny, kept things extremely light, was extremely touching.''
He added: ''[He even] cried a little bit. He did. And then everyone did. And it was the perfect tone for the night.''
Justin, 44, and Jennifer, 41, tied the knot at their lavish home in Bel Air, California, in front of 75 friends and family - including stars such as Ellen DeGeneres, Orlando Bloom and Sandra Bullock - just seven weeks ago.
And although they've been dating since 2012, the handsome actor feels more ''settled'' now they're officially hitched.
Asked if getting married has made him feel any different, he said recently: ''You know, I feel like I've earned it in a way. I appreciate it and I look forward to being good to her.''
He added: ''It's hard to explain but it's a nice feeling, a settled feeling. It just feels really good.''
