Peaches Geldof has publicly apologised for naming the co-defendants of disgraced singer Ian Watkins in a post.

The Lostprophets frontman appeared at Cardiff Crown Court in Wales on Tuesday (26Nov13) and shocked fans by pleading guilty to a number of sickening offences, included the attempted rape of a baby.

Watkins was in the dock alongside two female defendants - the mothers of the two children abuse by the rocker - and they also pleaded guilty to a number of charges.

The pair remained anonymous to protect the identity of Watkins' young victims - but British socialite Geldof took to Twitter on Thursday (28Nov13) and named the two women.

The offending tweet was later deleted, and following a warning from Britain's Attorney General that identifying sex abuse victims is illegal, Geldof took to her social media account once again to apologise.

In a series of posts ,she writes, "I deleted my tweets... and apologise for any offence caused as at the time of tweeting (I) had only seen everyone tweeting the names at me so had assumed as they were also up on news websites and the crown courts (sic) public file that they had been released for public knowledge. Will check my facts before tweeting next time. Apologies and lesson learned."

Watkins and his co-defendants are due to be sentenced on 18 December (13).
