Sinead O'Connor's marriage is over, again!

After her whirlwind Las Vegas wedding to Barry Herridge on December 9, Sinead announced the two were splitting after only 17 days of marriage — only to call off the breakup eight days later after what she called an intense night of "mad lovemaking."

But this time the Nothing Compares 2 U singer says it's over for good, and in a new diatribe posted on her blog the 45-year-old singer says she blames the media in Ireland for the destruction of her marriage.

"These people, along with others caused enormous damage deliberately and maliciously to my innocent flower of a husband, purely because he was with me. And so his association with me became something very bad for his life," Sinead wrote.

"Guess who had a mad lovemaking affair with her own husband last night?" the Irish singer wrote, noting that "mother----- who dont like it ...so me all happy!! me love me hubby ...he love me ...f--- who no like it ...God is good!"

O'Connor explained that she and Herridge, 38, will try to perfect their marriage over time, after their first try resulted in a split after just 16 days.
