Lopez took to Instagram to share a picture from the day that featured her boyfriend, her 9-year-old twins Max and Emme, and Rodriguez's daughters Natasha, 12, and Ella, 9.

"Happy Sunday everybody!" she captioned the adorable photo. "#sundayfunday"

Rodriguez and Lopez have only been dating a couple of months (their talked-about romance reportedly began in February), but that hasn't stopped either star from going all-in on the relationship. After several weeks of traveling together, the couple began making highly-publicized outings together in New York and Los Angeles before making their red carpet debut together at the 2017 Met Gala in early May.

This isn't the first time their kids have hung out together, either. Rodriguez and Lopez brought their children along for their Easter weekend in the Dominican Republic, where the cute kids reportedly hit it off.

Lopez shared a photo of her daughter, Emme, and Rodriguez's daughter, Natasha, hanging out on the picturesque trip.
