Guests including Jermaine Dupri, Bryan Michael Cox, T.I. and Tiny, Toya Johnson, Monica and more were greeted with a photo booth as they entered the establishment, before making their way to the main area, where a DJ was set up for karaoke — one of Nelly’s favorite hobbies.

As karaoke got started, one of Nelly’s friends began to sing Case’s “Touch Me Tease Me (Remix)” before the Grammy-nominated hip-hop star himself surprised the crowd and finished the song. He then sang “Missing You,” one of Nelly’s favorite songs, and the birthday boy joined in to sing along.

Later in the evening, Ashanti shared a video to Instagram of Nelly appearing to have a blast while performing King George’s “Keep on Rollin’.” Rasheeda left a comment on the post, writing “A MF vibbbbbbeeeee!!!!!”

At the end of the night, Nelly was presented with blue, three-tiered vanilla cake (printed with his name in blue letters and a photo of the rapper) as he was serenaded with “Happy Birthday” by his close friends, loved ones and Grammy-winning girlfriend.

He also celebrated her birthday by posting a sweet Instagra, tribute. Alongside a montage of photos and video clips of the couple, Nelly wrote, “One time for the birthday girl…. Such a beautiful and incredible person inside and out and one of the hardest working women I know.”

The pair recently reunited after dating on and off for 10 years between 2003 and 2013. In September, Nelly confirmed they were back together during an appearance on the Boss Moves with Rasheeda show, saying the reconciliation “surprised both of us.”

“It wasn’t anything that we planned. We both were pretty much doing what we do,” he explained. “But sometimes being separate, you understand one another more. You could be like, ‘Well yo, let me exactly see maybe what they see.’ We all can be defensive sometimes in our own relationships. We know we wrong but we going to stand on it, you know what I mean? But we all a victim to that.”

Ashanti, meanwhile, sent her own not-so-subtle hint that she and Nelly are a couple again, carrying a clutch bag printed with a 20-year-old photo of the couple at the 2023 MTV Video Music Awards in September.

At the event, she told PEOPLE she and Nelly are “in a great space,” adding, “Everything is positive. [We’re] having a lot of fun.”
