Jason Derulo’s Ex Jena Frumes Wears Red Bikini During Family Beach Day

Jason Derulo‘s ex Jena Frumes brought the heat to South Beach this weekend … flaunting her beach body in a hot red bikini while hanging with her baby daddy and their son.

The fam was photographed at the W South Beach — a five-star hotel in Miami Beach this weekend … heading out to the sand where they had their own VIP cabana and sunbeds.

Check out the pics … Jena stripped off her cover-up dress shortly after arriving at the beach — revealing her steamy swimwear underneath.

Derulo’s near by in his t-shirt and board short … laughing big while watching their son — also named Jason — dig around in the sand.

Miami seems like a location of convenience for the family to congregate … ’cause JD had a couple shows down in “The Magic City” this past weekend.

Jason played LIV Nightclub Saturday — a favorite of celebs hanging in South Florida — and then the home of the Miami Heat, the Kaseya Center Sunday.

If you don’t know … Jenna and Jason split up in September 2021, about four months after their son was born.

Jena claims that Jason’s cheating ultimately ended their relationship … though it still seems they’re on good terms — given their time out and Jason buying her a $3.6 million home in 2022.
