Jermaine, 62, gushed about the birth in an Instagram post on Tuesday, uploading a photo of a blue baseball with “It’s A Boy!” written in white letters.

“Congratulations to my baby sister Janet and Wissam! @janetjackson #muchlove #bigkiss #mynephew #jermainejackson,” Jermaine captioned the photo.

Janet’s father, Joe Jackson, uploaded a slew of old photos of himself with Janet to his website as he congratulated the singer on the birth.

“Making me a grandfather again !” Joe wrote. “Wishing you all the love and happiness a father could wish a daughter.”

Janet married Qatari businessman Al Mana in 2012, and news of their first child’s impending arrival was reported in May after the singer sparked speculation in a Twitter video.

Janet shared a baby bump photo exclusively with PEOPLE in October saying, “We thank God for our blessing.”

In May, Jermaine said that his little sister would be a great mother “because she is very tough, very strict.”

He added: “But I tell her, ‘If you need any parenting skills or baby skills, let me know because I’m the best diaper changer there is on this planet, still to this day.’ ”
