Maria Sharapova's burgeoning stable of investment holdings and endorsement deals grew bigger this week, as the four-time Grand Slam champion announced she'd be joining sunscreen maker Supergoop! as an equity owner. According to Bloomberg, Sharapova will not be the face of the brand but will act primarily as a megaphone to the masses on the subject of skin care education.

“I was actually a fan of Supergoop before I met Holly—I found it at Sephora,” Sharapova told Vogue Magazine. “I’ve been in the sun for as long as I can remember for my job. I’ve spent years training in Florida... And when I met Holly [Thaggard, Supergoop's founder and CEO], her message was such an important one—raising awareness and making sure that many people are knowledgeable about skin cancer, that it is the leading cancer [in the United States], and that it’s preventable.”

“It’s been a very seamless partnership because I really believe in the brand itself,” Sharapova told Bloomberg in a feature that ran on Thursday. “It started as a sunscreen company as opposed to a makeup company that just incorporated sunscreen products in their collections.”

In addition to her candy enterprise, known as Sugarpova, the Russian's deals with companies such as Head, Nike, Porsche, Tag Heuer and Evian enabled her to make $23 million in off-court earnings, according to Forbes. But Sharapova's deal with Supergoop is her first in the beauty sector.
