The 44-year-old said that she has already started fixating over her appearance, reported Digital Spy.
"I'm not going to lie about this. There are lots of times I look in the mirror and I see that gravity has taken hold.
Or I suddenly see my face on a phone or on Skype and it's like a Spielberg special effect and you just scream, 'Who is that?" Minogue said.
"Sometimes, I forget I am 44 and think, 'I must get those hot pants out of retirement' and then some mornings I look in the mirror and I see 94 not 44. That is the reality before the make-up. And midriff tops are definitely out for good," she added.
Minogue also said that she would consider having cosmetic surgery, arguing that it is no different to using make-up.
"I haven't gone down that route yet and I don't know whether I will but I'm not against it.
"We put make-up on every day, we tint, pluck, wax, we do anything to make ourselves look as good as we can and I think it's pointless being hypocritical about something that if it's done well can be really good," she added.
