On the same day that Jennifer Lopez managed to avoid the big pregnancy question from Diane Sawyer on Good Morning America, the singer faced another tough interviewer – David Letterman.
But the host, who relentlessly peppered Paris Hilton with questions about her jail stay recently, kept mum when it came to asking Lopez about a possible visit from the stork.
As PEOPLE witnessed during Tuesday's late afternoon taping of CBS's Late Show with David Letterman, the TV host did ask Lopez, 38, about her mother Guadalupe – who parented with tough love, her famous daughter explained.
Though clearly respecting Lopez and husband Marc Anthony's privacy, Letterman, 60, nevertheless asked if J.Lo would be as tough a parent as her own mom if she ever started a family.
"If I can be as great a mom as she is," Lopez responded, "then I will be all right."
As a father himself – of son Harry, who turns 4 next month – Letterman acknowledged that parenting is challenging, and anything that may have worked when he was a kid is now totally irrelevant.
"You think you're prepared to have a child – you're not – throw it all away," said Letterman, which prompted Lopez to laugh.
"So," he went on to ask her, "the idea of having a family is daunting, isn't it?"
"Yeah," she answered with a broad grin, "it is."
