Tennis star Maria Sharapova reveals plans to release autobiography in 2017

Tennis star Maria Sharapova has announced that she hopes to release her autobiography in 2017.

The Russian sportswoman, who has won five Grand Slam titles so far, will give a tell-all account of her career and life off the court.

On Facebook, Sharapova wrote: "I am very excited to share my story with you. It is real and raw and there are no limits. We have already started working and speaking to all the interesting characters that have been so influential in my life.

"It is amazing how many things I am learning and re-living while working on this book. Writing has been a passion of mine ever since I realized math was not my favorite subject, and it gave me a chance to express my feelings when I didn't have many people to communicate to as a young girl."

Sharapova is working with American writer Rich Cohen on the book.
