The tennis star and the Reddit co-founder got hitched in New Orleans on Thursday at a star-studded ceremony.
Sources told PEOPLE that the happy couple tied the knot at the Contemporary Arts Center in the Louisiana city.
The couple are said to have had a Beauty and the Beast theme, and guests entered the ceremony to the tune of Be Our Guest.
Beyonce’s bandmate Kelly Rowland, Vogue editor Anna Wintour and Arrow actor Colton Haynes were all in attendance at the nuptials.
What’s more, Serena’s fellow tennis star Caroline Wozniacki was present at the wedding alongside her new fiance, NBA player David Lee.
Around 250 guests were said to have been invited to see Serena tie the knot to her perfect match – who she has two-month-old daughter Alexis Jr. with – and the nuptials are rumoured to have cost more than $1 million.
One of those attendees was Jay Z, who is said to have had to rush off to North Carolina immediately afterwards to perform his next tour date.
A source told the Daily Mail: “Serena and Alexis have spared no expense on their dream wedding.
“They have hired the best of the best and can’t wait to get married in The Big Easy. It’s a special city for Serena and somewhere she has always loved.”
Serena and Alexis started dating in 2015 and announced their engagement in December 2016.
