A bitter three-year battle between Sinead O'Connor and "Irish Times" columnist John Waters for full custody rights of their daughter Roison ended over the weekend on a tragic note.

O'Connor decided to turn over the toddler to her father, just four days after the singer attempted suicide by swallowing 20 valium tablets. Waters' attorney, Kevin Brophy, told MTV News Wednesday that due to an injunction gagging both parties from discussing the case, they couldn't issue a comment.

However, in an explicit interview published Saturday in London's "Daily Mail," O'Connor says that she decided to sacrifice her right to custody to preserve her own sanity.

The "Daily Mail" reported that during one heated court hearing last week, a distraught Sinead spat in Waters' face. Ironically, O'Connor's own father won a landmark case as the first Irish father to ever be granted custody of his children from Sinead's mother. Sinead retains full custody of her 12-year old son Jake, from her former

marriage to drummer John Reynolds.
