Jennifer Lopez's daughter has found a new best friend (and twin) in Alex Rodriguez's daughter

Blending families can be difficult -- but things look promising for Jennifer Lopez and Alex Rodriguez!

While the headlines suggest their relationship is moving at a rapid pace, it appears that Lopez and Rodriguez have very smoothly and successfully introduced their respective families. Both are parents to kids under age 13 -- Lopez is mom to Emme and Max, both 9, while Rodriguez has Natasha, 12, and 8-year-old Ella -- which could have been a recipe for disaster. But that definitely hasn't been the case!

Lopez shared a photo of her daughter and one of Rodriguez's looking like total sisters in the Caribbean, with Emme perched on Natasha's back. If their brunette buns and tan skin weren't enough, they even have shockingly similar faces! Take a look and say these two don't already look like they were separated at birth.

The crew spent Easter at the Dominican Republic, and although wedding bells are still (probably) long off, it's promising that the Lopez-Rodriguez offsprings are loving their time together. There are sure to be many more family vacas to come!
