The 'Move' singer announced her engagement to the 1D heartthrob in August after she was spotted flashing a gorgeous ring on her engagement finger while attending the world premiere of One Direction's movie This Is Us.
During an appearance on ITV's Daybreak today, the blonde-haired star confessed: "I haven't got a wedding dress or started planning anything yet!"
But, she admitted she had already started thinking about what she wanted on her big day and, being a popstar, it's no surprise music is the first thing on her list!
"I really really hope Little Mix [perform at the wedding] and Steve Perry from Journey. That would just be my dream. I need him!"
She added that bandmate Jesy Nelson will probably be the one who "tells all the stupid jokes" at the reception.
Little Mix were on the ITV show to perform new single 'Move', which they showcased on The X Factor results show at the weekend. Of course, they shot to fame when they became the first group to win the show.
They had words of support for the latest X Factor eliminees, Kingsland Road. . "They are such lovely guys," said Jesy. "I think they'll do really well. I hope they do, anyway."
Jade Thirlwall added: "We were well gutted [they were eliminated]. They were one of our favourites so we wanted to take them out [after the show] and make them feel better."
