Documents submitted to Companies House - obtained by Britain's The Sun newspaper's Bizarre column - show that the three existing members gave Jesy a cool $2.6 million (£1.9 million) for her share of Eternal Magic Touring, a firm that handles their touring expenses.
In addition, Jesy received $1.6 million (£1.2 million) for her part of Eternal Dance Media, which deals with their music and ad deals. The deal was done in July.
Before the payout, the two companies had over £12 million - with $6.6 million (£4,884,910) in Eternal Dance Media as of New Year's Eve 2020 and $10.3 million (£7.6 million) in Eternal Magic Touring as of 31 August (21) - in their accounts.
Jesy Nelson fell out with her former bandmates following her solo debut.
She launched new single "Boyz" after leaving the all-girl group. The single sampled P. Diddy's hit "Bad Boys for Life" and featured Nicki Minaj. It also featured Diddy's cameo in the music video, but the single release was marred by black-fishing accusations, which Jesy vehemently denied.
"We're not talking any more. It is sad but honestly there is no bad blood from my side, and I still love them to pieces and genuinely wish them all the best," Jesy said.
