Kelis says her 11-month-old son is like a "little shrunken man".
The singer gave birth to Knight, her first child with rapper Nas last year. The couple split before the baby was born, and their divorce was finalised in May.
Despite the couple`s bitter split and acrimonious spousal and child support battle, Kelis doesn`t regret becoming a mother, and constantly wonders why she didn-t have children earlier.
"I`m so in love with this funny little creature," she told the USA Today newspaper. "Being a mother is literally the best thing in the world, and I absolutely love it.
"He`s got a lot of personality. He`s hilarious. He`s like a little shrunken man."
Kelis insists there are "absolutely" more children in her future, but she is not looking for another boyfriend at the moment. She is too busy focusing on her upcoming summer tour with Swedish R&B singer Robyn, and raising Knight.
The star is also busy promoting her new album Flesh Tone. She loved recording the record and says fans who buy it expecting to hear melancholy songs about her divorce will be disappointed.
"I was recording before a lot of that happened, and after it happened, I just continued writing and doing what it was that I was doing," she explained.
"I was writing to tracks that I loved and I was writing lyrics that just naturally came to me. There wasn`t any kind of master plan as far that went."
