Solange – who is engaged to music video director Alan Ferguson – is reportedly set to tie the knot this weekend, and about 50 family and friends joined the happy couple in NOLA for a pre-wedding bash at the Indywood Cinema.
Solange, 28, and Ferguson, 51, showed a film they made of how they met before playing the movie they saw on their first date: Mahogany, a '70s flick featuring Diana Ross.
"It was pretty adorable," Hayley Sampson, who owns the film house with brother Will, tells PEOPLE. "They were talking about how they met and that they bonded [over] this film and then showed everybody the movie."
As for the bash's treats, partygoers enjoyed daiquiris from local sandwich shop Gene's Po-Boys and drinks mixed by bartenders from the nearby go-to Oxalis.
The ready-to-wed pair have a history with the theater. Ferguson discovered Indywood Cinemas on his own when he saw a documentary and cult film there and then returned with Solange.
The bride-to-be's older sister attended the fête solo. "It was really nice to meet her," Hayley says. "She's a lovely person."
The "Partition" singer stunned in an all-black ensemble with a blue jacket, while her younger sister rocked a cream dress and gold heels, with fiancé Ferguson matching in a beige suit.

The rumored wedding weekend marks a return to New Orleans. Back in January, matriarch Tina held a star-studded 60th birthday soiree in The Big Easy. Then the Knowles clan returned this summer, appearing to have made up following Solange and Jay Z's elevator scuffle in May.
And it sounds like her brother-in-law's absence Friday has nothing to do with bad blood.
"What's important is that my family and I are all good," Solange told Lucky for its August issue.
