The 35-year-old tweeted: "Ahh big thanks to my spice girls melc,geri and emma for all the baby well wishes! Love you! Xxxxx"
And as you'll notice, there's conspicuously no mention of Posh, who also happens to have one in the oven herself at the moment.
There were reports of tensions between the pair of them earlier this year when it emerged that Mel had asked Vicky if she could borrow a couple of dresses from her fashion range to wear on her reality TV show It's a Scary World - and got turned down.
But when pressed on why Posh had been excluded from her thank-you tweet, Mel said: "I love and support all my spice girls always have!!!"
Which isn't really an answer as to whether Posh had failed to congratulate her. So we know where our money is.
What do you think? Is there a rift between them? Comment below please...
