We may see too much of certain members of The Saturdays due to wardrobe malfunctions, but Una was happy to have fun in the sun with her top off.
Una frolicked in the sea, recreating Dirty Dancing style moves with boyfriend Ben Foden.
One holidaymaker told the News Of The World: “Una was a sight for sore eyes as she nipped in and out of the water.”
The couple were on holiday in Ibiza at the time.
