Serena Williams finds her life-long mixed doubles partner

Tennis great Serena Williams is tying the knot.

Williams announced her engagement to Alexis Ohanian on Thursday, posting a poem on Reddit that she accepted the proposal of the social news website's co-founder.

Williams' agent, Jill Smoller, confirmed the engagement in an email to The Associated Press.

Williams, 35, has been dating Ohanian, 33, for over a year.

Her poem:

"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

This time he made it not by chance

But by choice

Down on one knee

He said 4 words

And I said yes."

Williams in July won Wimbledon for the seventh time to tie Steffi Graf's record of 22 Grand Slam titles. In September she passed Roger Federer for most all-time Grand Slam match victories, winning her 308th in the U.S. Open.

No wedding date has been announced.
