Perrie Edwards and Zayn Malik reportedly want completely different weddings.

The engaged popstar pair are currently two of the biggest names in music, and will no doubt have a bash that will be attended by the celebrity elite.

But while Zayn, 21, is said to want a small family gathering, Perrie can't make up her mind about how her big day should play out.

"If it was up to Zayn, it'd be just the two of them with close family. But Perrie's imagining things on a massive scale; she wants a castle or to hire a private island," an insider divulged to British magazine Now.

Zayn popped the question to 20-year-old Perrie last year, with the Little Mix singer showing off a sparkler when she attended the London premiere of One Direction's movie This Is Us in August.

While Perrie has admitted that she "might be a bridezilla", she seems to have enlisted the help of her mom when it comes to wedding themes.

"Perrie keeps changing her mind - one minute she wants a Disney themed wedding, then an intimate do in the UK. Her mom and friends are putting ideas in her head, showing her videos of huge weddings on YouTube. Zayn lets them get on with it but deep down he'd prefer something a bit more low-key," the source added.

Despite not deciding on a venue, Perrie has let slip that her Little Mix bandmates Jade Thirlwall, Jesy Nelson and Leigh-Anne Pinnock haven't necessarily made the bridesmaid cut.

"Who said they're bridesmaids? They're not even invited!" Perrie recently laughed to the British edition of OK! magazine.

"That was made up," she added about the bridesmaid rumours. "I think everyone just assumes, because we're so close. I don't know what's going on yet. I've got such a big family, and I know every girl in my family is going to want to be a bridesmaid. And most of my family are girls!"
