Matthew and Matt said Jennifer's wedding to Justin Theroux at their Bel Air mansion on 6 August came as a surprise to them too.
Speaking about not making the guest list, 48-year-old Matt told People: "If she wanted me there, I would have been there."
Friends stars Courteney Cox and Lisa Kudrow attended the nuptials which saw around 70 guests watch Jennifer and Justin exchange vows.
"I think they're a great couple," said Matt. "I think she's happy. And that's all I care about is that Jen's happy,"
Matt continued to say that the Friends cast - himself, Matthew, Jennifer, Courteney, Lisa and David Schwimmer - will always be a special little family.
Matthew, 45, added: "It was a surprise to me as well. They're a lovely couple, and I'm happy for them. I wasn't invited. So what can you do?"
American radio and television personality Howard Stern has already spilled the beans on what happened at Jennifer's wedding.
Speaking on his SiriusXM show, Howard didn't give away any details about the dress but revealed that Jimmy Kimmel actually officiated the wedding and how a Sia song was Jennifer and Justin's first dance.
But just how did they keep it a secret? "It was always called a birthday party," revealed Howard. "Whenever you got an email, it was a birthday party. They're so secretive that they even had the wedding on a Wednesday because nobody gets married on a Wednesday... Everything is always top secret."
