Jennifer Lopez and Alex Rodriguez enjoyed a pool day with their kids over the weekend.

Lopez, who is mom to twins Emme and Max, and Rodriguez, who is dad to daughters Natasha and Ella, combined their families for a casual "Sunday funday" outing.

"Happy Sunday everybody!! #sundayfunday [photo by] @lacarba," Lopez, 47, captioned a photo on Instagram of the group.

Rodriguez, 41, posted a picture on his own account of himself cozying up to Lopez.

"Happy Sunday! #downttime," he wrote.

Lopez shares Emme and Max with ex-husband Marc Anthony, while Rodriguez shares Natasha and Ella with ex-wife Cynthia Scurtis.

Lopez and Rodriguez were first linked in March, and confirmed their relationship the same month.

"[Their kids have] really bonded and become good friends," a source told E! News in April. "A-Rod's older daughter, Natasha, is like a big sister to J. Lo's twins."
