Photos: Janet Jackson's estranged husband is all smiles as he cradles their baby son on a walk with his nanny

Janet Jackson's estranged husband Wissam Al Manna was spotted in London with their six-month-old son. The billionaire dad was all smiles as he took his son to enjoy the sunshine in a park.

Accompanying the Qatari executive director was a black woman believed to be the child's nanny. Janet was nowhere in sight and that's no surprise, considering they are currently in the process of getting a divorce.

Janet's representative earlier revealed that the 51-year-old singer has hired help at home and her husband has been with her through it all.

Wissam seemed pretty hands-on with his child and held on to baby Eissa all the time, refusing to release him to the nanny. The nanny followed closely behind, carrying the baby's bag.
