The doting mum appeared to be in a reflective mood as she posted the snap taken from their summer holiday, captioning it: "My world".
The photo is thought to have been taken on their holiday this summer when the family were in Greece. It shows a beaming Emma, Jade, Tate and Beau, standing on the beach for an evening out.
The beautiful family are even colour coordinated for the occasion, all wearing white outfits to show off their holiday tans.
While she never confirmed the idyllic holiday destination that the family went to at the end of July, fans suggested that she was staying in Halkidiki, Greece.
Emma was sure to keep her fans and famous friends in the loop by sharing photos from the holiday including one of Beau paddling in the sea.
It's been somewhat of a big week for the 42-year-old. On Monday, she announced that she will be reuniting with her Spice Girl bandmates Melanie Chisholm, Melanie Brown and Geri Horner for a six-date tour in 2019.
However, there will be one notable absentee from the live shows – Victoria Beckham, who has decided not to rejoin the group, although she will make an appearance when the girls play in London.
The fashion designer did show her support on social media though writing on Instagram: "I won't be joining my girls on stage again but being in the Spice Girls was a hugely important part of my life and I wish them so much love and fun as they go back on tour next year.
"I know they will put on an amazing show and the fantastic fans past and present are going to have a wonderful time!"
Emma, meanwhile, was so excited about the comeback she leaked some news about the announcement a few hours early during her radio show with Jamie Theakston.
The bubbly blonde was chatting on Heart FM, and said: "It's so exciting. Everything will be announced just after three o'clock today on social media.
"You can go to @spicegirls but don't look at me anymore because I might just blurt it all out."
She also shared a throwback photo of herself as Baby Spice on Instagram writing: "Let's get this party started @spicegirls."
It's been an exciting week for fans of the 90s pop band. During an interview on Heart Radio this morning, Mel B let slip that Victoria Beckham will join the girls when they play at Wembley Stadium next year.
Fans, including superstar Adele, have been expressing their excitement about the Spice Girls upcoming tour.
Tickets are set to go on sale at 10.30am on Saturday 10 November, so here's everything you need to know about how to join the party…
