It's official! Solange Knowles, the sister of R&B superstar Beyonce, has tied the knot with her fiance Alan Ferguson in New Orleans on Sunday (Nov. 16).

According to PEOPLE, the couple were married in front of 200 guests who had to wear white outfits. Solange and Ferguson said their "I Do's" at the Marigny Opera House at around 2PM ET.

Guests in attendance included her brother-in-law Jay Z, Beyonce, Blue Ivy and of course, the family matriarch Tina Knowles. Solange's son, Julez, from her previous marriage to Daniel Smith, participated in the couple's nuptials as well.

"Beaming. Calm. They looked pretty calm, relaxed on their wedding day," an onlooker told PEOPLE. "Definitely happy."

Before the wedding, the pair rode matching white-painted bicycles to the chapel. Solange wore a cream-colored pantsuit with a cape and a plunging V-neck designed by Stephane Rolland. Meanwhile, Ferguson was dressed in a white suit and black shoes with a gold toe cap.

On Friday (Nov. 14), the couple held an intimate pre-wedding shindig at NOLA's Indywood Cinema where they screened a film on how they met before playing the Diana Ross flick 'Mahogany,' a movie they watched on their first date.

From the photos taken at the wedding, everyone looked amazing and the newlyweds look like they were 'Drunk in Love.' See what we did there?

Congrats to Solange and Alan Ferguson. We wish them many years of marital bliss.
