Her brother Jermaine Jackson has now confirmed to People magazine that Janet is expecting a baby.
He said: “My sister Janet is my baby. She is fine but she’s having a baby. A baby having a baby. We look at her like our little baby and now she’s grown and having a baby.
“I’m proud to be an uncle and I can’t wait to see how this baby is going to look.”

Jermaine, 61, said his younger sister would make a great mum.
“She’ll be a great mother because she is very tough, very strict,” he said.
Janet, who married businessman Wissam Al Mana in 2012, turns 50 this month.
