Pregnant Leigh-Anne Pinnock admitted filming music videos with their "big bellies" will be more difficult because of their lack of options.
Both Little Mix stars Leigh-Anne and Perrie Edwards announced their pregnancies within a week of each other.
The pregnant singers choreographed and starred in the dazzling music video Heartbreak Anthem.
They transformed into gorgeous angels alongside their third bandmate Jade Thirlwall who kept their secret in the early stages of their pregnancies.
Speaking about the difficulties of filming while pregnant, Leigh-Anne detailed the struggles in a new interview on Capital Breakfast with Roman Kemp.

Asked what music videos were next, she said: "Oh god, well honestly what could possibly be next? I mean, we don’t have many options with these big old bellies."
Heartbreak Anthem's music video blew fans away with its stunning visuals.
But behind the scenes, Leigh-Anne confessed it was "hard" filming with the wings because they were "so heavy".
She added: "Those wings were so heavy! Like, honestly there was a point in the video where we are bending over like this with them because they were that heavy because they were mechanical.
"So whenever the mechanic device was on us it was like “oh!” management had to be like “that’s enough now, we’ve got to stop it” because it just got too much! But I really hope people appreciate that and see the work we put into that, because it was hard!"
They have taken their gorgeous baby bumps to the star-studded BRIT Award red carpet where they were the first girl band to ever win British Group at the ceremony.
Leigh-Anne and Perrie have set their hearts on bringing their babies along on tour.
She said: "Well the bubbas are going to be obviously of a certain age so we’re just going to have to have a creche on tour basically."
Recently, Jade revealed exactly how she helped the girls keep their pregnancy a secret during filming.

She said on a TikTok Q&A: “Do you know what cracked me up though? Being in rehearsals for ‘Confetti’.
“Me and Leigh-Anne were pregnant at the time and so out of breath, but we didn’t want anybody to know, like choreographers and things.
“We didn’t want anyone in the room to know so Jade was going ‘Oh, my back’ and she was joining in! Leigh-Anne was going ‘My back hurts’ and Jade would go, ‘Oh, my back, I know, my back is gone!’”
It comes after Jesy Nelson recently announced she was going solo just months following her swift departure from Little Mix.
The star said she quit the band after being in a girl band took a toll on her mental health.
Jade, Leigh-Anne and Perrie have continued their legacy by banding together as a three-piece.
