Serena Williams has more titles than you can name, but she got a new one Thursday: fiancée.

Williams is engaged to Reddit co-founder Alexis Ohanian, according to CNN, which received confirmation from Ohanian's agent. The couple first began dating in the fall of 2015.

Ohanian reportedly popped the question while the two were vacationing in Rome, and Williams first announced the engagement in the Reddit forum "r/isaidyes."

"I came home/A little late/Someone had a bag packed for me/And a carriage awaited" Williams wrote in her Reddit post. "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/This time he made it not by chance/But by choice/Down on one knee/He said 4 words/And/r/isaidyes."

Ohanian also wrote a Facebook post saying, "She said yes," with a link to Williams' Reddit post.

With her Wimbledon title in June, Williams tied Steffi Graff for the most Grand Slam titles in the Open era with 22. Her first opportunity to break Graf's record will come in January's Australian Open.
