Emma Bunton and Mel C exchanged hungover texts after Victoria Beckham's birthday.
The former Spice Girls were reunited when the fashion designer celebrated her 40th with a bash at the Arts Club in London in April.
Pictures emerged of Emma and Mel looking a little worse for wear and the blonde singer can still recall how she felt the morning after.
"[It was] brilliant fun," she grinned.
"I got a bit drunk; it was so embarrassing. Mel C and I were texting each other the next day: 'I can't believe it...'"
She went on to add that Mel was definitely the "drunkest Spice Girl" there.
It was a good opportunity for Emma, 38, to let her hair down. She raises young sons Beau and Tate with her fiancé Jade Jones, and the pair are also busy planning their wedding.
Recently Mel, 40, joked Emma's wedding would be a good chance to put the stylish Victoria in a terrible bridesmaids frock.
"She is such a little plotter! I love her!" Emma laughed when she heard about her pal's evil plan.
"Jade and I are the worst organisers you'll ever meet. I just don't know where to start. I don't even know if I want the wedding at home or abroad."
The star added that her kids are growing up "too fast" and that the eldest, Beau, is a huge fan of Spice Girls hit Wannabe.
