0120-lauren-b-bushnell-splash'Bachelor' contestant Lauren Bushnell still has a ways to go to the final rose, but she's a total winner in a bikini.

Lauren B. hit the beach in Cabo San Lucas with her family.

There are still 17 ladies left in the 'Bachelor' house this season -- and Lauren, a flight attendant, is definitely a frontrunner ... with fans, anyway. There are even rumors she won the whole thing.

Lauren's next one-on-one date with Ben H. better require a bikini! For her, not him.
