Naomi Campbell shows off her age-defying body in a bright red bikini on holiday with billionaire boyfriend Vladislav Doronin in Florida.

The 39-year-old supermodel looked supremely toned as she snuggled up to her man during an afternoon stroll along Miami Beach.

Naomi made an eye-popping appearance at Paris Fashion Week recently when she hit the catwalk in a daring see-through corset.

Naomi swears by tantrums to keep her in such great shape (possibly.)
