The 52-year-old singer - the sister of the late legendary Michael Jackson - has admitted she's been sent some "crazy" things from her supporters over the years but the most disturbing thing came from a man who posted her a picture of his erect penis and bodily fluid and told her that he wanted to get her pregnant.

Speaking on Big Boy TV, the brunette beauty was asked what's the "craziest thing a fan has done?" and she replied: "Oh there's been a couple. One sent me a picture of himself with an erection and a jar of semen so he could get me pregnant because I was supposed to have his child."

Janet has 18-month-old son Eissa with her estranged husband Wissam Al Mana and she is convinced the tiny tot has saved her from depression.

She explained recently: "The height of happiness is holding my baby son in my arms and hearing him coo, or when I look into his smiling eyes and watch him respond to my tenderness. When I kiss him. When I sing him softly to sleep. During those sacred times, happiness is everywhere.

"Happiness is in gratitude to God. Happiness is saying, 'Thank you, God, for my life, my energy and my capacity to grow in love.' "

The 'Together Again' hitmaker believes her issues with the mood disorder stemmed from her feeling "inferior" as a child, while also coming up against racism and sexism.

She said: "I struggled with depression. The struggle was intense. Low self-esteem might be rooted in childhood feelings of inferiority. It could relate to failing to meet impossibly high standards. And of course there are always the societal issues of racism and sexism. Put it all together and depression is a tenacious and scary condition. Thankfully, I found my way through it."
