But Kate Upton has now turned her swimsuit expertise to design - and Beach Bunny recently launched her creations as part of their new Kate Upton for Beach Bunny collection.
The 5'10" model is proving that she is more than a pretty face with the skimpy beachwear, mixing glamorous diamanté and detailing with revealing cuts and bold colour.
White hot: The model-turned-designer said she loves the bikini's embellishments that make her 'feel sexy'
'I love all the embellishments and especially the lingerie details because they make you feel so sexy.'
The Kate Fatal Flowers bikini is a black number with ruffled flowers, finished with jewels at their centres. Its revealing bikini bottoms are side-tied with black and silver cord.
Not just a pretty face: Kate Upton models and designs for the California-based swimwear label
Itsy bitsy: The model has been busy - her Beach Bunny range launched within days of her becoming the cover star of Sports Illustrated's coveted swimsuit edition
First seen as part of a sneak peek of the model's designs, the Kate bikini went on show at last year's Miami Mercedes Benz Fashion Week.
Fine honing, an extra design and several other fresh colours gives the new range more shape.
Pretty in pink: The Ms Upton-designed range, announced last year, launched in February. Frills, diamante details and transparent panels are part of the new line
The California-based label said it was 'thrilled about the design collaboration.'
Beach Bunny's CEO, Angela Chittenden, said of the new muse: 'She is sexy, yet confident and her fun loving and down to earth personality are traits that represent the Beach Bunny woman and brand as a whole.'
It is not the first time a big-name model has designed for the swimwear label, last year saw Kim Kardashian and her sisters turn their hand to creating costumes for the brand.
Looking good: The California based model is certainly filling her time and has advertising deals with hamburger makers Carl's Junior and Hardee's
Ripped jeans: The company said it is 'thrilled' to have the 19-year-old on board as a designer
Suits you: Ms Upton has modelled for the label since 2011 and follows in the Kardashians' shoes after the sisters last year designed a range for Beach Bunny
We imagine the entrepreneurial model's magazine covers and endorsement deals will not end there.
