Brunette bombshell Kaia Gerber sure seems to know how to unwind over the busy holiday season.

The Chanel supermodel, 20, was seen posing in a skimpy string bikini yet again as she relaxed South Of The Border in sunny Cabo San Lucas on Mexico's West Coast.

The 5ft10in looker proved to have one of the most enviable bodies in the business as she highlighted her 24inch waistline while sunbathing on a white foam lounge chair by a swimming pool.

Also on the luxury vacation was her A-list mother Cindy Crawford, 55, and her Casamigos founder father Rande Gerber, 59, who is close friends with George Clooney.

But there was no sign of Kaia's rumored new love interest Austin Butler, whom she was seen leaving a home with on Friday morning in Los Angeles.

The look was a chic mustard yellow color - which was very popular in the 1960s - with a triangle top that had very thin straps over her shoulders.

The briefs were worn low on the hips, making the most of the Malibu High School graduate's impressive abs, and seemed to have a thong design on the backside.

Also on her back were two brown spots which may be tattoos. Kaia already has quite the collection of inkings on her body, including a heart, an angel, and the words Strawberry Fields.

Kaia wore a beige straw hat with brown sunglasses as she carried a red book, a bottle of mineral water, and her white case cell phone.

The budding actress, who has appeared in American Horror Story and Sister Cities, went for a dip in the swimming pool after reading her book.
