The tennis champion announced the news in an Instagram post on her 35th birthday, sparking a flood of well-wishes from friends and fans.
“Precious beginnings!!!” she captioned her social media post. “Eating birthday cake for two has always been my specialty.”
Sharapova shocked tennis by retiring from the sport at 32, having reached No. 1 in the world rankings, won five grand slam titles and amassed a personal fortune estimated at $300 million.
The Russian walked away from professional tennis in early 2020, unable to overcome injury issues that plagued the latter stages of her career.
In December 2020 Sharapova got engaged to British art dealer Alexander Gilkes — the ex-husband of Meghan Markle’s best friend Misha Nonoo.
Sharapova reportedly previously dated Maroon 5 frontman Adam Levine and also had relationships with NBA star Sasha Vujacic and fellow tennis pro Grigor Dimitrov, before she and Gilkes became an item in 2018.
Sharapova recently joined the ranks of Russian athletes hitting back at her homeland’s invasion of Ukraine, pledging to donate to Save The Children’s crisis relief fund.
“With each day that goes by, I am more and more heartbroken and deeply saddened by the images and stories of families and children affected by this escalating crisis in Ukraine,” she wrote on Instagram last month.
“I am donating to Save the Children’s crisis relief fund, an organisation working tirelessly to provide food, water, and aid kits to support those in need.
“Please join me in making a donation. I pray for PEACE and send my love and support to all those affected.”
