The supposedly estranged duo rode the waves in Puerto Rico, with Cardi holding onto Offset from behind.
Cardi wore a sexy white two-piece bikini which she showed off on social media earlier in the day.
The Grammy nominee was in town for the Electric Holiday Concert in San Juan, Puerto Rico.
Cardi announced her split from Offset on Instagram earlier this month. "We just grew out of love," she said as the reason for why things ended between them.
