Mel B has reportedly been moaning to pals about Geri Horner's pregnancy announcement

A source told The Sun on Sunday newspaper: "Of course Mel is thrilled personally for Geri but she's very fiery and in the moment she found out her temper flared and she said a few choice words to pals she probably shouldn't have. Within minutes of Geri gushing about her good news on Instagram, Mel unfollowed her.

"It's a good job Geri is so zen nowadays, because if she'd heard about Mel's moanings things could have escalated.

"However, Mel's desperate for the reunion to go ahead so when she realised Geri was still totally on board with doing Spice stuff next year everything seemed to be smoothed over."

Geri, 44 - who has a 10-year-old daughter called Bluebell from a past relationship - revealed recently she is expecting her first child with husband Christian Horner.

It was reported that Geri and the Formula One boss are doing their best to involve her older offspring as much as possible with her sibling.

A source said: "Geri wants to include Bluebell in the pregnancy as much as possible to ensure she doesn't feel left out - especially after being an only child for so long.

"She's taken Bluebell along to scans and has given her the role of helping her and Christian choose a name for her new sibling, as well as picking out accessories for the nursery. Bluebell is really excited about having a sister or brother to play with."
