The 14-time MLB All-Star, 47, made their romance Instagram official on Saturday, posing with Cordeiro and his two daughters Natasha, 18, and 14-year-old Ella in front of a beautifully decorated tree during a Christmas party in New York City.
“From our hearts to yours, Merry Christmas,” Rodriguez wrote in the caption.
He and Cordeiro, a fitness instructor and founder of Jacfit, were first romantically linked in October.

Rodriguez opened up in September about the kind of father and partner he wants to be after his 2014 suspension for using performance-enhancing drugs.
The couple began dating in 2017, and they announced their engagement in March 2019.
Meanwhile, the former New York Yankee remains close with Natasha and Ella’s mother Cynthia Scurtis, to whom he was married from 2002 to 2008.
In April, the four traveled to Memphis together, along with Scurtis’ husband Angel Nicolas, to see the Grizzlies take on the Minnesota Timberwolves, of which Rodriguez is a part owner.
