Now, Geldof is being investigated for sharing the mothers' names via social media (she later deleted the Tweets).
A court order was made to grant lifelong anonymity to two children whose mothers allowed Watkins to abuse them.
But yesterday Miss Geldof, daughter of Boomtown Rats singer Bob, broke the order by naming their mothers to her 161,000 followers on Twitter.
The Attorney General said a possible criminal offence had been committed. South Wales Police are investigating.
Only 24 hours previously, Miss Geldof had been lecturing the Press about invading people’s privacy.
