0328_courtney_robertson_the_Bachelor_bikini_launch'Bachelor' winner Courtney Robertson is at it again ... flaunting her ridiculously hot body at the beach, but this time she kept her bikini on. 

If you recall ... Courtney won the Ben Flajnik edition of "The Bachelor" after they banged in a now famous "ocean sex" scene from season 16. Alas, like most of these TV romances, the relationship didn't last. Courtney spent Easter alone in Malibu ... looking hot!

Courtney's message in these pics is pretty clear -- I'm available!
