Williams first shared the news through her verified Reddit account, posting a sweet poem along with cartoon sketch of Alexis getting down on one knee.  The poem reads:

I came home

A little late

Someone had a bag packed for me

And a carriage awaited

Destination: Rome

To escort me to my very own “charming”

Back to where our stars first collided

And now it was full circle

At the same table we first met by chance

But by choice

Down on one knee

He said 4 words


I said yes

Serena Willaims

In response to the poem he wrote in a comment, “And you made me the happiest man on the planet.”

Reportedly the pair met for the first time in Rome in May 2015, when she played the clay court tournament before the French Open. They were spotted together at dinner in San Francisco in November 2015.

Over the years, Ohanian has been the biggest cheerleader of Williams on social media, posting about her accomplishments both on & off the court.
