Ahead of returning to her tennis career, supporting husband Alexis Ohanian shared with the world Serena Williams' newfound title outside of sport as "Greatest Momma Of All Time."

Her time off from being tennis' "Greatest Of All Time" came about after the news of her pregnancy to now 5-month-old daughter, Alexis Olympia Ohanian Jr.

A unique gesture

The billboards, which all feature images of baby Olympia and her mom, state "GREATEST MOMMA OF ALL TIME."

The Reddit co-founder and husband of Williams added "@olympiaohanian & I wanted to welcome her back to tennis.

Designed them myself, with some help from Jr. #GMOAT."

Williams, 36, and Ohanian, 34, tied the knot in November 2016 after having dated for only a year. The tennis pro revealed the news of her pregnancy by accident across Snapchat when she was 20 weeks in, before later confirming the story. The couple then welcomed their baby girl September 1, who Williams told Vogue prefers to call by her middle name, Olympia.

Ohanian designed the advertisements with AdQuick, which were displayed across California highway just in time to be seen on the drive up to her upcoming tournaments.

Williams clearly appreciated the surprise for as she took to Instagram to thank her husband. "I love my surprise so much for them. I feel so special. Love you both."

The tennis star also honored her little girl recently in a Gatorade ad. Williams said, “You’ll find the courage to stand tall, work harder and speak louder on whatever playing field you choose in life.

So keep playing, my girl. Keep playing."

Back to tennis

After her maternity break from being the crowned greatest mom, the athlete will soon get back to her game just 5 months later as she competes in the 2018 BNP Paribas Open in March. It will be her first set to play since giving birth to Alexis Jr.

Williams shows definite commitment to the sport as she continued to train throughout her pregnancy, still willing to face competitors head on even after the complications that ensued during her delivery that involved an emergency C-section.

The tournament, kick-starting on March 5, is her next chance to gain a title since her win at WTA Tour at the Australian Open in January 2017. The triumph, marking her 23rd Grand Slam singles title, was achieved when she was two months pregnant.

It will be the first time in two years that either Serena or Venus Williams have competed on the team, but this year both sisters will be making their mark. I think we are all happy to say we are excited to see her back on the court.
