EXCLUSIVE

Liziane Gutierrez doesn't need Chris Brown or Jason Derulo to party it up -- she can get wet and wild all by herself.

We got the Brazilian model in Marina Del Rey, where she jumped right into the water in her thong ... and a see-through top.

As for Chris saying she's "too ugly" ... c'mon now.
