The 'I'm Outta Love' hitmaker claims the majority of women in the industry turn to the procedure when they reach the milestone.
She said: "When you're looking at 40-year-old women, and they look as great as I look, then there's no way that they're not using it. Sorry.
"But they're not going to admit it because it's none of your business. I don't really care to say. 'Yes, I'm using it'. And everyone is in shock because I didn't look like I used it.
"I'm like, 'Everyone is using it. What are you on, crack? They're just not telling you.' But you can believe them if you want. I know what a 40-year-old's face looks like without doing that."
However, the 47-year-old singer doesn't blame women who undergo the procedure from keeping it to themselves as it is "not anyone's business".
She added to the Mail Online: "They have every right not to tell. It's not anyone's business what we do to our bodies, and what we do to our insides or outsides. It's our secret as women.
"Botox, if done right, should not look like you've had it done. Most of the people you're seeing and noticing have it done are having too much. And that's my personal opinion, that's why I can admit that yes I am still doing Botox. But just the slightest bit to stop the lines from being so deep. It doesn't freeze it."
