After all, you don't know the ins and outs of another woman's personal circumstances and, quite frankly, it's none of your business.
So we're rather surprised that US chat show host Wendy Williams told Nicole Scherzinger she had wasted her "good years" by not having a baby in the seven years she dated Lewis Hamilton.
Williams said in an interview with the singer this week: "Because you're 37, I was like, 'this is a woman who spent seven years of her life breaking up and getting back together'.
"Poor us. They [men] can have babies whenever they want. You know what I mean? Those are seven years you can never get back."
Scherzinger awkwardly laughed the comments off, saying: "Everything happens for a reason, I'm a girl of faith and a strong believer, seven years was a long time but..."
At this point Williams interrupted Scherzinger, saying: "And the good years down here." She then gestured to her womb.
The studio audience may have laughed at the comment, but Scherzinger looked less than impressed.
"I think whatever you experience in life and in your relationships, you're obviously meant to grow from it," she said.
Williams was later criticised on social media for her lack of sensitivity.
The controversial interview comes after model Chrissy Teigen opened up about her fertility struggles, saying she was sick of being asked when she was going to have a baby in interviews.
"Anytime somebody asks me if I’m going to have kids, I’m like: ‘One day, you’re going to ask that to the wrong girl who’s really struggling, and it’s going to be really hurtful to them'," she said.
"And I hate that. So, I hate it. Stop asking me."
