The singer finds it funny how much One Direction fans adore her boyfriend.
Zayn Malik's girlfriend doesn't get jealous about other girls being interested in dating him.
She told The Sun newspaper: ''I just think it's funny. You have to trust each other. Me and Zayn are really happy. We see each other quite a lot, the only time we don't is when he's In America. It's really hard. But I trust him.''
She said despite his busy schedule and constant travelling, they make their relationship work by staying in contact regularly.
She said: ''It does get hard when you don't see each other. It does make it more special when you do see each other though.
''You just have to make sure you call and text each other all the time and tell each other what you've done each day and stuff.''
However Perrie thinks that their often long distance loves is what puts the Spark in their romance and also confessed that she ignores criticism about their pairing online.
She said: ''It's when you don't talk to someone that you start missing them.
''As far as his fans go, there's always going to be one or two bad comments, but you've just got to ignore it. About one in 100 are bad ones.
''I just read all the good ones -- most people are really happy that we're in a relationship and happy.''
