The singer, 38, said she shares a different kind of relationship with her other group members Victoria Beckham, Melanie Chisholm, Emma Bunton, and Geri Halliwell and revealed meeting them secretly at times, reported Daily Express.
"We all talk. I was just in London and we all had tea together. It was a private tea, nobody saw us. We talk about our kids and regular stuff," Mel B said.
"We all have different relationships with each other but we've been together for 20-odd years so it is a long time," she added.
She did not even tweet any birthday greetings to her former bandmate despite regularly doing so in previous years.
