2015 isn't off to the greatest start for Caroline Wozniacki. Less than a year after fiancee Rory McIlroy broke off their engagement, the tennis star has been dropped as an underwear model for the design firm JBS.

That also brings to a close the company's partnership with Wozniacki in producing a line of underwear designed to provide athletic support and comfort while maintaining a sexy appeal. Until now, Wozniacki was the headlining name attached to the company.

By ending its relationship with Wozniacki, the design firm will divert all of its resources toward expanding its relationship with Cristiano Ronaldo, a global soccer star who, in an ironic twist, was attracted to the idea of underwear design and modeling by Wozniacki herself.

"He had seen how Caroline dared to be pictured in only her underwear that we had made for her, and he liked it," said JBS director Morten Alstrup, according to 101 Great Goals. "We had hoped to grab a market, but the impact of CR7 has been far, far greater than we dared dream of."

And so brings to a close the all-too-short underwear modeling career of one of tennis' most popular athletes.

Wozniacki's underwear line is still for sale and featured on the JBS website. It's unclear if she will be removed from the site, or if her products will continue to be sold until the inventory is sold off.

Either way, don't expect to see more of this anytime soon:
