"They give each other space," a source tells PEOPLE of Jamie Foxx and Katie Holmes in this week's issue

In recent months, Jamie Foxx and Katie Holmes have taken their relationship more public than ever since they were first seen together in 2013. They even wrapped up 2018 with a Dec. 28 yacht outing in Miami, and rode a pair of Jet Skis the next day.

“They chilled, swam and enjoyed the sun and beach activities,” a source tells PEOPLE in this week’s issue of their Miami vacation. “It was a chance to get away and enjoy each other.”

The Robin Hood star, 51, then spent New Year’s Eve in Florida with his children Corinne, 24, and Annalise, 10, while Holmes, 40, rang in 2019 by skiing with daughter Suri, 12. The low-key couple aims to balance their time together with family and work.

“Katie and Jamie see each other as frequently as they can,” the insider says. “They have known each other for years, and both turned out to be great parents, so they also have that in common. They are dedicated to their careers. Plus they give each other space.”

“They are both serious-minded, organized and dedicated to their careers,” the source says.
