Iskra Lawrence shows off her sizzling curves in a series of bikini throwback snaps as she admits she is missing modelling shoots

She is an ambassador for body positivity retail brand, Aerie.

And Iskra Lawrence shared a series of throwback snaps from previous modelling shoots with the brand, as she admitted she was missing being in front of the camera.

The model, 30, looked incredible as she bit into a brownie in one snap, wearing a blue and pink zigzag bikini top, teamed with a pair of hot pink bottoms.

The two-piece highlighted Iskra's incredible hourglass physique, while she opted for a fresh-faced look with minimal make-up and wore her blonde locks loose.

In another clip Iskra put on a playful display on the beach wearing a khaki crochet bikini top with a pair of floral bottoms.

The mother of one tousled her locks as she beamed for the camera while on location for another Aerie shoot.

Iskra appeared to have had an incredible time on past shoots, as she also posted a clip of her dancing with another model in their lingerie.

It comes after the British beauty, who is an advocate for body positivity, filmed herself trying to close the buttons on the jeans and when the trousers would not do up, she urged fans to not be hard on themselves when their bodies change.

Iskra looked sensational as she wore a nude bra and the light coloured jeans, which she jumped and tried to close with gusto. 

Maintaining her smile, she penned over the top: ''Tried on these jeans that still had the tags on. Quickly found out they ain't gonna fit...

'My body has changed a lot this year. Can you relate? Well it's whatever. Weight and size is not constant. You and your body will go through many changes...

'Be gentle with yourself. This is your home. It's the only one you got, and even if it's hard to love sometimes it loves you.'

Alongside the video she penned a caption reading: 'It’s crazy how quick some fabric can attack our self esteem. Well NOT TODAY JEAN...

'My self love journey has not been perfect or linear. My body has continued to support me through every season of my life...  

'I refuse to give up on loving myself. Since giving birth to my child everything has changed, my mindset, outlook in life and my physical self...

'I found a new respect for my bodies abilities. And I’m in complete awe of what it has created... I can no longer let insignificant struggles or negative thoughts mean anything when I know the incredible journey we’ve been through together...

'So next time you cant fit into your old jeans or try on a pair in a size you usually are and they don’t fit, it’s whatever...

'Because we are doing our best, and will continue to show up imperfectly. Hope this is a little reminder today that you are loved and will always be enough'. 

Iskra became a first-time mother back in April, when she and Philip Payne welcomed the birth of their baby son.

The model recently admitted that her exercise regime hasn't been 'consistent' since giving birth but said she was 'in awe' that her body has given her the gift of motherhood.
