CHER has joined a growing list of celebrities who are publicly opposed to the controversial proposed Shannon LNG project, in County Kerry.
The singer openly targeted the Irish government as well as Taoiseach Leo Varadkar, who is supposedly a big fan.
She took to Twitter and Instagram to voice her criticism of the fracking plans.
"I know the Irish people don't need actors and singers from Hollywood getting into their business but it's because we care and we have had experience with the kind of people and companies who frack and sell the gas," she wrote.

Last month, American actor Mark Ruffalo publicly called for the Irish government to dump the plans, even accusing them of "killing Americans".
Included in Cher's post was a copy of a letter than she and other celebrities had signed and sent directly to Mr Varadkar himself.
This will come as a blow to Varadkar who joked last month that he hoped Brexit negotiations could be wrapped up swiftly so that he could catch Cher's concert in Dublin.
It was signed by director Michael Moore, Mark Ruffalo and other groups who are anti-fracking.
Specifically, it referred to the proposed Shannon LNG project in Co. Kerry that would use fracked gas imported from the U.S, even though fracking is banned in Ireland itself.
Varadkar hasn't declared yet whether he will give the project the go-ahead, but has suggested in the past that the project could ensure "energy security" for Ireland.
