Donatella Versace ''trained'' herself to hide her insecurities.

The fashion designer has admitted she's suffered from a lack of confidence throughout her career and spends her nights dwelling over her decisions.

When asked to name the hardest part of her job, Donatella - who is the Vice President of the Versace Group and chief designer for the Italian label - told the New York Times newspaper: ''It's my self-esteem. I trained myself to hide my vulnerability and my insecurity for a long time. I give in to these two emotions only when I am alone. At the end of the day, I'm just kind of thinking, 'Is it good enough?' The next day I wake up and I'm like, 'Oh, yeah, that was fine.' But usually, in the evening, I have that half an hour that I think I did everything wrong.''

The fashion icon, 59, also claims to be the ''most antisocial person'' and despite a constant stream of party invites and shows to attend she prefers spending time in her apartment.

She said: ''My private life, nobody believes me, is really - when I finish my work, working here, I'll go to a show or after-party, but when I get home from those things, I lock myself in the apartment and I don't want to hear anything. I'm the most antisocial person you can think about. Even if nobody believes me.''

Donatella also shared the details of her day to day routine and confessed to having an entire ''glam squad'' to keep her looking red carpet-ready.

She explained: ''I wake up very early in the morning - 6:30 to 7 - and do a little bit in the gym. Not because I love it but because I need to do it to keep my body healthy. And I have a light breakfast.

''I have a glam squad, who help me to do hair and makeup every morning. I don't look like this when I wake up, you know. I need a little help. And then I go to the office and talk to my assistants, go through all the mail. And then I go straight downstairs and just wander around.''
