Katie Holmes and Jamie Foxx are continuing to spend time together in Miami
Making a splash!
Holmes, 40, and Foxx, 51 — who have mostly kept their four-and-half-year romance away from the public eye — had an adventurous day on Biscayne Bay aboard red and blue jet skis.
Riding in front of Foxx, Holmes was seen smiling as the duo took in the sights.
One day earlier, the pair were spotted relaxing on a private yacht, with Holmes rocking a black bikini and Foxx sporting a simple white t-shirt.
The couple’s Florida fun comes weeks after they were seen celebrating the actress’ 40th birthday in New York City.
During their Dec. 18 outing, the couple were joined by Holmes’ mother, Kathleen A. Stothers-Holmes, and stopped by popular dessert destination Serendipity 3, where they enjoyed a strawberry sundae and frozen hot chocolates.
“Katie was all smiles,” a source told PEOPLE. “She and Jamie were flirty.”

Though both have had busy schedules in the last few months, they’ve made efforts to see each other regularly. In November, the two spent time together in New Orleans, where she was filming The Secret and he was working on an untitled sci-fi thriller for Netflix. Foxx visited Holmes on her set and they also enjoyed a romantic dinner date at Restaurant R’evolution in the city’s French Quarter.
“Their relationship seems so much more serious this year,” a source told PEOPLE in this week’s issue, on newsstands now. “Katie and Jamie keep having public dates, and although they try to not be photographed together, they are clearly not as concerned about keeping their relationship private.”
“Katie always acts super-excited and giddy when Jamie is around,” added an insider. “They are very cute together.”
