Tammy Lynn Michaels has accused her former partner Melissa Etheridge of spoiling Christmas for their two children.
In a poem posted on the internet she insinuated the rocker is causing her money problems by holding up the child support money she owes to her.
Since ending their nine-year-long relationship back in April 2010, the former couple have become embroiled in a bitter and public custody battle over their twins.

As part of their post split settlement, Melissa is obligated to pay Tammy $23,000 per month.
But on her blog site Hollywood Farm Girl Tammy has complained the checks are very slow to arrive.
In a cryptic poem she also claims her lack of funds might affect the Christmas presents she can buy her six-year-old twins with the singer, Johnnie Rose and Miller.
She writes: 'Fascinating you know - secrets, they are.
'People, places, things and accounts, houses, waived rights AND relationships, money - secrets are sick - a sign of an illness within - disease.
'Playing games with money - phoney baloney - hide and seek - can you find the ball under the clam shell?
'Christmas is coming - chase the check - chase the check - chase the check - can't - catch it - oh watch the girl go - empty stockings and tiny boxes - don't worry - i'll teach them what's important.'

However there is a bright spot to the prose, as she goes on to claim that despite her frequent griping, she does not care about money and that she may be the only one with morals.
She writes: 'Nothing close to - what i have to chase in the stupid mail box - but rather - what is in the heart - which could never - never never ever be found in a mail box anyway.
'Millionaires in their mansions - tricking with trusts - hiding money from Paul behind Peter - just to steal from the minor in the end - integrity is a mystery in - the town of gold dust - pyrite - fool's gold.
'At times i do feel - as narcissistic as this sounds - that i might be the only - one - with a moral compass - this side of the Indiana State Line.
'Tell me it's not true - no - show me - show me - someone show me it's not true.'
