While Jennifer Lopez and Alex Rodriguez still have to iron out their future wedding venue details, one thing's for sure: Jennifer's 11-year-old son, Max, will play a huge part in her special day. In an interview with Entertainment Tonight, the 50-year-old singer and actress confirmed that Max will "of course" be the one to walk her down the aisle.

But Max won't be the only one to take part in the ceremony. According to a source, Jennifer Lopez's 11-year-old daughter, Emme, as well as Alex Rodriguez's girls — 14-year-old Natasha and 11-year-old Ella — will also have important roles.

"For them both, they are still all about their family with the four kids. Their initial strong attraction for each other would have quickly faded if they had not been able to come together as a family," said an insider close to the couple. "Their kids all accepted each other and got along from the beginning."

Moreover, both Alex and Jennifer's kids are thrilled about the engagement and excited to make things official. "It's always tricky when you merge families, but Jennifer and Alex did a great job from the start," explained the source. "The kids are amazing together. And they have wanted Jennifer and Alex to get married for a long time. They will all definitely be a huge part of the wedding." Eek! We can't wait to see the photos!
