One Direction's Zayn Malik Declares His Love For Little Mix Girlfriend Perrie Edwards On Twitter

Zayn Malik's relationship with Perrie Edwards has gotten all serious - it seems they have uttered those three little words to each other.

The One Direction star has publicly declared his love for the Little Mix singer as she celebrated her birthday.

But seeing as this is the digital era, he did it via the medium of Twitter to his four million followers.

He tweeted: "a very special happy birthday to my baby perrie ! :D x mwah love you x"

Young love. Don't it warm your cockles?

It was revealed the couple were dating in May, when Zayn was caught leaving Perrie's house after a 'sleepover'.

The pair then confirmed their romance, but have remained pretty tight-lipped about it since.

When she appeared on This Morning, Perrie said it was easier being in a relationship with someone who was also in a band.

She told Holly Willoughby and Phillip Schofield: "It's more understanding because you get it and it's more exciting when you see each other.

"But when you don't see each other, you're so focused in the studio, our mindset is on what we're doing, so it's important to be like that."
