Speaking to the new issue of Star magazine Magazine, Perrie said: ''Zayn and I are at the stage where we feel fully comfortable with one another.''
When asked whether he preferred her with or without make up, she added: ''My boyfriend says he likes me either way.
''I have good skin like [bandmate] Jesy [Nelson], so going make-up-free doesn't bother me too much - if I know the paparazzi are about I carry large shades with me.''
When it comes to beauty tips, Perrie also likes to keep things simple, with her top beauty tip being to use water.
She added: ''That, and cleansing and moisturising will get your skin really glowing.''
The blonde beauty may credit the heartthrob for her increase in confidence but she admits their relationship has become so strong due to their tight friendship.
Speaking previously, Perrie said: ''Zayn is so lovely. You know things are good when you can't wait to see the other person. It's a sense of friendship. The main thing I looked for is if he's fun to be around, if I can have a laugh with him.''
