Cindy Crawford is one hot mama!
The supermodel was spotted on vacation with her hubby Randy Gerber in St. Bart's on Thursday.
The brunette beauty looked gorgeous wearing a black bikini, while also makeup-free, as she enjoyed the sun and surf with Gerber.
It's crazy to think that Crawford will be turning the big 5-0 tomorrow -- doesn't she look better than most women half of her age?!
Cindy made waves earlier this month when she announced that she was retiring from modeling.
"I'm sure I'll have my picture taken for 10 more years, but not as a model anymore," she told Rhapsody Magazine just a few weeks ago. "And that's okay. I've done it. I've worked with all these incredible photographers. What else do I need to do? I can't keep reinventing myself. I shouldn't have to keep proving myself. I don't want to."
But there's another model in the family now -- Cindy and Randy's daughter Kaia is already following in her famous mama's footsteps!
"Kaia would be modeling even if she weren't modeling," Cindy confessed. "All the girls are modeling. They are not dependent only on how a photographer sees them. They have a direct relationship with their fans."
