When's the wedding?!

J.Lo and A-Rod spent their Sunday chillin poolside with their respective kids, and it's pretty clear they're in it for the long haul. The singer's twins Max and Emme appear to get along seamlessly with the baseball star's daughters Natasha and Ella, which is always the biggest hurdle when you're blending a family.

Jenny from the Block is reportedly so smitten with her beau that she would happily say yes to a proposal from the MLB legend, E! News reports.

"J.Lo and A-Rod are getting very serious and talking marriage. J.Lo wants a future with A-Rod. J.Lo would marry A-Rod if he asked. She is head over heels for him. They get each other in so many ways," a source dished to the outlet.

"They are perfect for each other. Their families love how they are together. She loves sharing her life with Alex. The kids all get along and it’s just one, huge happy family. [Rodriguez] is very supportive of Jennifer and admires and supports how hard she works. They share this amazing respect for each other," another source dished to People.

We'd be shocked if an engagement didn't happen by the end of summer!
