Last year, former world number one Carol Wozniacki revealed she was starting her own underwear line and now she has let fans see what happened behind the scenes as she posed for photos and videos.
Wozniacki calls the collection 'this is me' and says that it is a product she is passionate about.
"For me it is very important to wear a good set of underwear," explains Wozniacki in the video.
"It is just important that you feel comfortable, it looks good, it matches your clothes and makes you feel feminine and sexy as well.
"I have my name on an underwear collection – it is just fantastic."
We are sure that golf star boyfriend Rory McIlroy has no complaints.
