Stacey Solomon shared a moving tribute to her older sister in honour of a special achievement.

Taking to instagram, Stacey posted an image standing hand-in-hand with her older sister, Jem, with the pair wearing co-ordinating pink summer dresses.

In a sweet message alongside the photograph, Stacey said spoke directly to Jem as she said, "For all of our lives you’ve looked out for me, protected me, lifted me up & been the best cheerleader I could have ever wished for."

What to read next

Now, however, Stacey said she got to do that for her sister instead. "To my big sister, my best friend, my guardian angel. Today is all about you, Stacey wrote, revealing that her sister had written a book.

"My sister wrote a bloody BOOK 😭 It’s amazing, I’m so so proud & today I got to be there to watch her launch it and shine her beautiful bright light in front of all of her family & friends and it was an absolute honour!" she wrote. "Good luck @label.lady.1 not that you need it! But to the moon and stars and back again! Forever and always."

Stacey also added, "I love you so much Jem honestly don’t know what I’d do without you."
