Ugandan businessman Shakib Cham Lutaaya celebrated Wednesday's birthday of his stepson Riaz Nasibu Abdul aka Prince Nillan.

The 32-year-old young man, Zari Hassan's husband, used his social media pages to celebrate the last child of the socialites on his birthday.

Prince Nillan turned seven on Wednesday, December 7. Shakib posted a cute video that showed him walking side by side with Prince Nillan in matching gray suits. "🎂🎁🙏🏻," he wrote in the video.

The two were seen walking together with beautiful smiles in the video. Shakib, who celebrated his birthday earlier this week on Tuesday, appears to get along well with Zari's children.

The South African socialite has five children from two previous relationships, Ivan Ssemwanga and Diamond Platnumz.

After dating for over a year, the businessman and mother of five married in October.

Zari Hassan celebrated Shakib and Nillan's special day, their birthday, on Wednesday evening. The 43-year-old socialite asked God to grant all their heart's desires in his message to the two.

"Help me wish my husband and my son a happy birthday. May the Almighty make all your wishes come true," Zari wrote on her Instagram page.

She accompanied the message with a photograph of Shakib and Prince Nillan dressed in matching gray suits.

They looked great together. Shakib turned 32 on Tuesday, December 5, and Prince Nillan turns seven today, December 6.

Zari Hassan and her ex-boyfriend, singer Diamond Platnumz, have a son named Prince Nillan. On the other hand, the socialite married Shakib in a glamorous wedding earlier this year.

On the other hand, the age difference between the mother of five and her husband has been a major source of contention among their fans since their relationship was made public early last year.
