Alex Rodriguez's daughter Natasha impressed his girlfriend Jennifer Lopez, with her singing this week.
The former MLB star shares Natasha and 9-year-old Ella with ex-wife Cynthia Scurtis, while Lopez is mom to 9-year-old twins Emme and Max.
The pair combined their families for a casual pool day Sunday.
"Happy Sunday everybody!! #sundayfunday," Lopez wrote.
Rodriguez and Lopez 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."
Life & Style reported in May that Lopez, Rodriguez and their children are "like one big happy family."
Lopez last released the album A.K.A. in 2014, and presently serves as a judge on the new NBC reality competition "World of Dance."
Rodriguez retired from the New York Yankees in August.
