Victoria Beckham ‘couldn’t stand’ her former bandmate, Geri Horner, according to Tom Bower.

The investigative journalist’s new book, The House of Beckham: Money, Sex and Power, which has been serialised by the Mirror before its release on June 20, takes a deep dive into the relationship of one of the most influential couples in the world, including what Victoria was like behind closed doors.

The mum-of-four, 50, has known Geri, 51, since the nineties when they shot to fame as Posh and Ginger Spice in the best-selling girl band. However, in recent years there’s been rumours of a rift between the pair, highlighted when Geri unfollowed Victoria and David earlier this year amid her husband, Christian’s work conduct allegations at Red Bull.

Speaking about their relationship during the Spice Girls’ fame, Bower claims everyone loved [David] Beckham, but “Victoria was different” adding: “Increasingly, she was outspoken and provoked retaliation.” He continues: “‘I can’t stand Geri,’ she said about her former best friend. ‘She is one of the most disloyal people I’ve ever known.’”

The book also claims the fashion designer mocked Geri for dating DJ Chris Evans, who she was in a relationship with in 1999. Bower claims: “Twisting the knife, she even scoffed at Geri for going out with DJ Chris Evans. ‘She’ll do anything to get publicity. Geri doesn’t care what she does as long as she gets in the paper.’”

It wouldn’t be the first time the Spice Girls have been accused of falling out. Back in 2002, Mel B claimed in her autobiography that she and Geri used to argue like lovers.

Meanwhile, Melanie ‘Mel C’ Chisholm was also involved in her own spat, writing in her memoir that Geri once got “clocked in the face” while trying to “keep the peace” during a fight between the two Mels.

In her second memoir, Mel B also revealed that she and Victoria fell out in the ’90s when, during a group holiday to Hawaii, Posh saw Mel B’s holiday fling pooing on the beach and called him “disgusting”.

In February, it was also reported by MailOnline that Geri had unfollowed Victoria on Instagram, however, Geri did celebrate her 50th birthday in April, although her husband Christian did not attend. Geri has been married to millionaire formula one Team Principal and CEO Christian Horner, 50, since 2015 and they share a son together. But as the mum-of-two stepped out of her limo – in trademark pristine white – to join Victoria at her party, Christian was nowhere to be seen.

However, it seems the F1 boss was forced to miss out on the fun due to work commitments – as the Chinese F1 was in full swing and he needed to attend.

Mirror Online has reached out to Geri and Victoria’s reps for comment.
