Solange Knowles knows the challenge of being a famous teen mother.
Knowles, now 21, welcomed son Daniel in 2004 at the age of 18 (she split with husband, former college football player Daniel Smith, after the baby was born).
"I'm sure a lot of people perceived that I was gonna be a young, irresponsible mom," Knowles told Usmagazine.com during a recent visit.
But Knowles pointed out, "I think that there are some moms who are 35 who are just as irresponsible."
What advice does she have for the 17-year-old mom-to-be Jamie Lynn Spears?
"You just have to make the best decisions for you," Knowles said. "You have to decide what's best for you.
"Who are we to say what's right and wrong for a person?"
To focus on raising her son, Knowles said she "moved to the country for a year" without any nannies or babysitters.
"My parents lived on a whole opposite part of the world," she said. "My son has been my focus ever since the day he was born."
"He's been the light of my life," she added, "the inspiration behind everything."
