Holly Willoughby showed her lookalike sister some love online on Friday.
The This Morning presenter took to her Instagram Stories to share a series of cute shots with Kelly Willoughby.
Reposting the original post from Kelly, 42, the ITV star added a sticker to her Story which read: "I love my sister."
In the sweet collage, the siblings can be seen seen posing for the camera in a variety of cheeky poses.
"Throwback @hollywilloughby @youmagazine #schoolforstars children’s book series," Kelly captioned the snaps taken with her famous sister.
Holly looked her trademark glamourous self in the shots - wearing a chic black lace top and her long blonde tresses loose.
The Dancing On Ice host commented on her sister's grid post, shared with her 33,800 followers on Thursday.
"Awwww love this," the star wrote underneath Kelly's upload.
The shot came about as the sisters collaborated on the School For Stars children's novel back in 2013, as well as Holly's latest spiritual venture, Wylde Moon.
Elsewhere on Holly's Instagram Stories on Friday, the popular presenter was in full promotion mode, as she celebrates the release of her new book.
The star shared a series of snaps from fans and friends enjoying her brand new title, Reflections.
Speaking on The One Show earlier this week, the wellness-loving businesswoman revealed her new book was all about reconnecting with different things and finding herself again.
She explained: "The thing is, I am very lucky and I am very blessed. I do have a wonderful family and husband, and work.
"I love my career but sometimes, when you are spinning all of these plates you forget to stop and just be still, and work out who you are in the middle of all of this craziness, and this bit that is going on.
"That is really just what happened, I just lost touch with myself I think."
Last month, Holly launched a brand new wellness website called Wylde Moon after being inspired during her stint hosting I'm A Celebrity in 2018.
"When I went to Australia to do ‘I’m A Celebrity…Get Me Out of Here! ’, I suddenly had three weeks without my children and for the first time in a long time, I didn’t really know what to do with myself," the mum-of-three wrote on the site's first blog in September.
"Australia is the land of alternative therapies, and the town that I was in truly had all kinds of things for all kinds of people.
"Through this wonderful kinesiologist called Josie, I really started to unlock pieces of myself and when I came back to England, I knew that I didn’t want to stop everything I’d learnt."
Last week, the TV star announced that her online boutique was now open - with sustainable scented candles being the first items available to buy.
Wylde Moon fans are now able to purchase a single wick candle at £40, a triple wick candle at £65, and a fragrance diffuser priced at £45.
"I’m so so proud of these products… deep breath… I hope you love them too. Head over to @wyldemoon and follow us for more information… thank you," Holly wrote on Instagram when promoting her new range.
