Serena Williams and her long term boyfriend Alexis Ohanian, co-founder of Reddit tied the knot in an intimate ceremony at New Orleans' Contemporary Arts Center on Thursday.

The star-studded guest list included Serena's sister Venus Williams, Ciara, Russell Wilson, La La Anthony, Kim Kardashian West, Beyoncé, Jay-Z, Ciara, Eva Longoria and the members of New Edition, who were playing during the reception.

Alexis took to Instagram to share a few snaps of their wedding and paid tribute to his new wife. 

He wrote: "You are the greatest of all time, not just in sport--I’m talking about as a mother and as a wife. I am so excited to write so many more chapters of our fairy tale together. And my whole life I didn’t even realize it, but I was waiting for this moment.And everything that I have done, everything that I am so proud of in my career, and in my life, for the last 34 years, pales in comparison to what we’re doing today. And I am so grateful, and I am so in love. (sic)
