They’re both expecting their first child, announcing they were pregnant just six days apart.
In a behind-the-scenes snap from the shoot for Kiss My Uh Oh, the singers can be seen with their blossoming stomachs on full display while they pose with bandmate Jade Thirlwall, 28, and singer Anne-Marie, 30.
Bumping along! Little Mix’s pregnant Leigh-Anne Pinnock and Perrie Edwards have showcased their growing stomachs in behind-the-scenes snap from new music video Kiss My Uh Oh
Leigh-Anne highlighted her bump in a tight beige skirt which completely covered her belly and was styled with a polka-dot white shirt and bright pink cardigan.
The mum-to-be wore her locks down, letting them cascade over one shoulder, and held onto a colourful handbag for the snap.
Perrie was also glowing in the image, with her bump being dressed in a skin-tight white T-shirt and black leggings.
She added a leopard print cardigan to her costume for the fun video and ensured to showcase her growing bump by standing slightly to the side.
Glimpses: The singers had teased a look at their growing stomachs in the fun music video, with them wearing the colourful costumes in the opening scene which was inspired by Bridesmaids
Joining the stars in the picture, Jade sported baggy trousers with a pale blue shirt tucked in and accessorised with a flat cap and neck pillow.
This costume was inspired by Melissa McCarthy’s look in Bridesmaids, with much of the video recreating famous scenes from the hit movie.
While singer Anne-Marie, who Little Mix have collaborated with on the track, looked stylish in a black and white striped crop top and high-waisted jeans.
The stunning quartet released the music video for Kiss My Uh Oh on Friday.

Filled with fun and laughter, the video recreates scenes from the 2011 movie, which told the story of Annie (Kristen Wiig) who falls out with bridesmaid Helen (Rose Byrne) while acting as Maid of Honour for her childhood pal Lillian (Maya Rudolph).
The video opens with a recreation of the plane scene, in which the bridesmaids jet to Las Vegas for the hen do.
Jade took on the role of Megan, originally played by Melissa McCarthy, Leigh-Anne played Becca (Ellie Kemper) Perrie was Rita (Wendi McLendon-Covey) and Anne-Marie starred as Annie (Kristen).

The video then moved on to the pair getting ready to go out and party, with the girls clad in Versace robes as they get ready together.
In the end pregnant Perrie and Leanne decide to stay at the hotel, while Jade and Anne-Marie are seen partying it up in the club with their entourage, complete with strippers and lots of dancing.
Jade, in this part of the clip, is wearing a thigh skimming black dress with her hair in a pony tail, and Anne-Marie is wearing an equally leggy white dress, signifying her bride-to-be status.
This much-anticipated collaboration has excited both Anne-Marie and Little Mix fans alike, and the song could well become the break up anthem of the summer

The four minute clip is directed by Hannah Lux Davies, whose directing credits include the video for Doja Cat’s Say So and the iconic thanku, next video from Ariana Grande.
The song, which samples the early noughties track Never Leave You (Uh Oh) by Lumidee, is about the liberation which comes from walking away from a toxic relationship.
The track is co-written with Kamille, who has worked with the likes of Little Mix previously.
