EXCLUSIVE: Janet Jackson Doing Well After Wissam Al Mana Split: 'She's So Happy With Her Baby'

Janet Jackson is completely focused on her son, Eissa, in the midst of her split from her estranged husband, businessman Wissam Al Mana.

A source close to the Jackson family tells ET that the 50-year-old singer is doing well despite the breakup, which came just three months after she gave birth to their first child together.

"Janet is ecstatic," the source says. "She's so happy with her baby and that's all she is focused on."

ET confirmed Jackson and 42-year-old Al Mana's split on Sunday, but an eyewitness tells ET that it seems as though Jackson moved out of their shared London home a month ago.

"Janet was very rarely seen leaving the house she shared with Wissam. A team of staff seemed to tend to all of her needs," the eyewitness said of Jackson's life in London, adding that the couple's staff included "two drivers, a housekeeper, her own personal assistant, a nanny and more." On the rare occasion the singer would venture out -- often to a florist or a children's store -- she'd usually bring along her personal assistant.

However, for the past month, only Wissam has been seen leaving the apartment, according to the eyewitness, and neither Jackson nor her assistant have been spotted at the property.

In exclusive photos obtained by ET, Al Mana, a Qatari-based billionaire, was spotted outside the home on Friday, as members of his staff brought children's toys and balloons into the house. The eyewitness speculates this may have been to replace items Jackson moved out with.
