Victoria Beckham, Geri Halliwell, Emma Bunton and Mel C (real name Melanie Chisholm) each took to their respective Instagram accounts to wish their beloved Scary Spice (born Melanie Brown) a happy birthday on May 29.
On her Instagram Story, Victoria shared a snapshot of her and Mel B hugging and wrote, "Happy Birthday @officialmelb Kisses!"
The heartwarming photo was taken during Mel B's celebratory dinner after she was awarded an MBE (Member of the Order of the British Empire) for her charitable work against domestic violence on May 4.
Emma also celebrated Mel B's special day by posting a collection of throwback photos of the pair together on Instagram.
"I get to call this strong, funny gorgeous woman one of my besties. How lucky am I," The Circle star boasted in her caption. "Love you darling, have the best day."
Meanwhile, Mel C teased the idea of a potential Spice Girls reunion in her birthday post.
"Happy Birthday Melanie! Hope you're having an amazing day," she shared. "I can't wait to share the stage again with you love ya xxx"
And, last but not least, Geri kept her birthday shoutout short and sweet, writing, "Happy Birthday !@officialmelb love you so much. Hope you have a amazing day !"
In response to the outpouring of love that she received, Mel B thanked everyone for their well wishes in an Instagram post of her very own. The sweet photo featured the Spice World star sticking out her tongue with the words "Happy birthday too me" written above her head.
"I don't really like my birthday day as my dad's birthday was Yesterday," Mel B explained. Her father, Martin Brown, passed away in March 2017. "God rest his soul I miss him beyond words could ever say always."
However, she noted that it was "good to celebrate the day your born no matter what's going on," adding, "so hey happy birthday to me."
