The 53-year-old supermodel strolled along the beach and flaunted her ultra-fit physique while on vacation in Tulum, Mexico. Macpherson paired her baby pink string bikini with a white sarong and wide-brimmed hat.
The newly single mother of two was eager to hit the beach when she arrived on Wednesday, adding a series of snaps, including one in which she looked effortlessly beach chic in a strapless white dress paired with an oversized straw bag and coordinating hat.
"Finally here... beach bound," the Australian model captioned the first snap of herself descending a winding staircase.
The model recently split from husband Jeffrey Soffer, after nearly four years of marriage. She was previously married to photographer Gilles Bensimon and has two children -- Aurelius and 19-year-old Arpad -- with French financier Arpad Busson.
