It's love - love!

Serena Williams is engaged to Reddit co-founder Alexis Ohanian, and the tennis ace announced the happy news on... you guessed it, Reddit!

"I came home. A little late. Someone had a bag packed for me. And a carriage waited. Destination: Rome," she wrote in a poem. "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 knee. He said 4 words. And I said yes," she added.

The couple met and began dating in October 2015 but have been super private about their relationship, so this comes as a surprise to many.

She's going from the court to the chapel!
