Rihanna is the perfect poster girl for Charlie by Matthew Zink thanks to her "natural confidence".
The fashion mogul has swimwear label Charlie by Matthew Zink and recently Barbadian beauty Rihanna posted a picture of herself in Instagram in one of his creations.
Matthew is flattered by her attention and the fact she calls his design her "favourite bikini of all time".
“Rihanna's sensuality and youthful energy make her the perfect muse for Charlie," he told GraziaDaily.co.uk.
"I think our styles help celebrate Rihanna's natural confidence and sexuality. I can't tell you how proud I am to have her as a #charliefan.”
In her picture, the singer is wearing the Andie two-piece, a yellow number with a white zigzag design.
The 25-year-old isn't Matthew's only fan - Kim Kardashian, Jennifer Lopez and Lea Michele have all been spotted in his bikinis.
According to the designer, a toned figure like Rihanna's isn't the only way to wear his creations.
“Enjoy it! Make sure you always have a high quality, simple, solid black bikini in your favourite silhouette,” he advised.
“I always find a bit of tan helps me get in the mood when I try on new styles. And never forget... every bikini is worn best with a smile.”
Matthew previously worked as design director for luxury lingerie label Victoria's Secret.
He went on to create his own lifestyle brand and subsequently his swimwear line.
“I have put so much energy and commitment into making the perfect string bikini,” he emphasised.
“I also take a simple timeless approach to swimwear to make sure you get the attention, not your bikini. In the end, people are sexy not clothes.”
