Little Mix began their invasion of the U.S. with an appearance on 'Good Morning America' today (Feb. 4).

The Brit girl group, whose new album 'Salute' hit stores today, performed breakout hit 'Wings' and new song 'Move' in the show's Times Square studios to an enthusiastic crowd of Mixers. They also dished on their upcoming tour with Demi Lovato and Perrie Edwards' engagement to Zayn Malik, and discussed what makes 'Salute' different.

"It's a lot more R&B, and we really focus on the harmonies and the beats," Jade Thirlwall told 'GMA' co-host George Stephanopoulos in a short interview segment. "We just want to everyone to listen to it, feel better about themselves and have a good boogie on down."

The darker, more mature followup to 'DNA' hit No. 1 on the U.S. iTunes chart shortly after the group's morning-show appearance. They celebrated the album's success with a couple of adorably ecstatic tweets:

Little Mix are preparing to join Lovato on her imminent Neon Lights Tour, as Leigh-Anne Pinnock gushed. "We are so excited. Who's coming to watch us?" she asked to loud cheers from the audience. "We can't wait. We're -- oh my gosh -- pumped!"

Stephanopoulos asked Edwards the millionth question about her upcoming wedding plans with One Direction's Malik. "No dates yet, not yet," she answered. "We're very busy, but we'll get there soon." As she spoke, 'GMA' aired the cutest shot of the couple we've ever seen, showing Zayn taking a selfie of the pair posing with Mickey Mouse (see it in the first clip below).
