Cher has cut off son Elijah Blue Allman financially, the 49-year-old claims. In court documents obtained by the Daily Mail on Thursday, Allman requested a reduction to the spousal support payments he gives estranged wife Marieangela King — and cited Cher as the reason why. He claimed the Grammy winner used to send him $10,000 a month but stopped doing so back in August 2021.

He alleged this comes out to $6,790 post-taxes. Elijah is currently required to send King, whom he wed in 2013, a monthly payment of $6,500. Instead, his lawyers have requested the number be dropped down to $1,651 per month. Getty Images Getty Images Want more celebrity and pop culture news? Start your day with Page Six Daily.
