Women are plucking nose hairs, shaving their toes and waxing their moustaches - but their boyfriends will never know.
According to a new poll the average female has eight embarrassing beauty secrets she hides from her partner.
The findings revealed today reveals women many spend hours taking hidden measures in order to look naturally beautiful.
Most men know their other half shaves her legs... but what about those toes?
Researchers found women hate the thought of their other half knowing their beauty secrets.
As a result, procedures such as hair removal from toes, chin, body and bikini line remain hidden.
A large majority of the 2,000 women surveyed would never let on to their partner if they were wearing body-slimming underwear or if they removed hard skin from feet.
The study shows many ladies would hate their partner to know they had to remove hairs from their noses on occasion, while others don't want him to know they often treat spots with toothpaste, or whiten their teeth.
