Rochelle Humes sweetly paid tribute to her younger sister Sophie Piper before the Love Island All Stars Final on Monday.

Molly Smith and Tom Clare were crowned the winners of Love Island All Stars, beating out her ex Callum Jones and his new partner Jess Gale.

Sophie and her loved-up partner Joshua Ritchie finished in third place, while Georgia Steel and Toby Aromolaran placed fourth, leaving Georgia and Harrison and Anton Danyluk in last place. 

The This Morning presenter, 34, took to Instagram to share a racy snap with Sophie, 24, and their other sister Lili Piper.

Rochelle flashed her washboard abs in a satin pink co-ord, teamed with a cropped white shirt.

Sophie cut a risqué display in a cut-out split ruffled dress and wore stylish cowboy boots.

Lili looked incredibly glamorous in a sexy sheer mini dress and flaunted her lingerie underneath the garment.

Captioning her post, Rochelle said: 'Speaking of Love Island... Baby sis has made the final.' 

Sophie and Lili did not meet her famous older sister Rochelle properly for the first time until she was 18.

The sisters grew up separately and ended up connecting through fellow Love Islander Kem Cetinay.

Rochelle's father Mark Piper left her and her mother Roz Wiseman when the star was just three years old.

He went on to have three more children, Sophie, Lili and Jake, with his new partner.

By pure coincidence, Kem went to school with Lili and approached Rochelle at an event after he found fame on Love Island.

Rochelle recalled the meeting during an appearance on Giovanna Fletcher's Happy Mum Happy Baby podcast. 

She said: 'I've never told anyone this before. Two years ago, I was at our management's Christmas party and Love Island's Kem was there.

'He was chatting away and said, 'I got to talk to you... as soon as I became a celeb, I promised my friend Lili that I would talk to you as she's your sister on your dad's side.'

'I knew of her and met up with her when I was five, but it was so complicated as they were a lot younger and my dad wasn't involved.'

Sophie previously spoke to MailOnline about getting back in touch with Rochelle, saying: 'There was a period where we weren't in contact. 

'It was weird growing up not knowing Rochelle but since we have spoken we speak every day so it is nice all of us being in each other's lives now.

'My middle sister Lili went to school with Kem so that's how we know him. Obviously he was at the same school as me. It's funny how it's all linked together.'

During Sophie and Josh's interview during the Love Island final Maya Jama, Josh shared that he full intends to ask Sophie to be his girlfriend, but insisted he wanted to introduce her to his family and friends first. 

After Molly and Tom were declared winners, Tom told host Maya 'my mind's blown', while Molly was visibly shaking as she shouted 'what the hell'. 

Speaking ahead of the final result, Molly admitted the Love Island experience has 'forced' her to be friends with her ex Callum.

She also said she was 'grateful' they've had the chance to gain closure on things, but insisted that there would be no 'fairytale ending' for them both.

Talking about navigating romance within the villa with her ex there, Molly said: 'I think obviously from the outside looking in, people won't understand.

'We're in an intense environment and you've got to get along so it kind of forced us to be friends.

'We probably wouldn't be at this stage on the outside, it probably would have just been a bit awkward, but I feel like it's got us to a place that we never would have gotten to, and I'm actually grateful for that.'
