Janet, 51, and record producer Jermaine, 45, dated for seven years until their split in 2009.
Another insider said: 'Janet is single. She is good friends with Jermaine. They share a very close and beautiful bond. He's been there for her and she loves that about him. Anything can happen in the future but right now she has a lot on her plate.'
The source added: 'She is doing great and feeling great on her tour. Her baby is by her side as much as she can allow it. She has people helping her out. She looks great and is always so grateful to everyone that helps her and works with her. She is very pleased how everything is going on tour.'
The 'Unbreakable' star who is currently on tour with her son Eissa, who was born just four months before her split from businessman Wissam, is said to be seeking full custody of her son, after her family accused Wissam of being verbally abusive to her during their relationship.
