Sinead O'Connor only announced two days ago she would wed her unknown boyfriend of three months in a ceremony on Thursday.
And true to her word, the eccentric Irish singer tied the knot for the fourth time in a quickie Las Vegas wedding on her 45th birthday yesterday.
She walked down the aisle with Irish therapist Barry Herridge, who she met online, at the famous Little White Wedding Chapel in Nevada's Sin City.
Sealed with a kiss: Sinead O'Connor married boyfriend Barry Herridge at the famous Little White Wedding Chapel yesterday, days after announcing their engagement
The ceremony lasted just 15 minutes and the couple invited no guests - even Sinead's four children - apart from the cameramen.
She dressed unusually girly and looked to have lost weight, looking more like her Nothing Compares 2 U heyday in the 1990s.
The tomboy wore a strapless pastel pink maxi dress and chunky pink metallic and silver heels.
But she failed to conceal her numerous tattoos, including a massive design on her chest, and is still sporting her trademark shaved head.
In love: Not much is known about Barry, a therapist she met online after a desperate plea by the singer for a decent man to come forward

The couple looked smitten with one another, sharing a passionate kiss for the cameras and staring into each other's eyes as they walked sown the isle after being pronounced husband and wife.
They cuddled up on a pink Cadillac - reminiscent of Elvis Presley's iconic car - before heading to a hotel in the gambling capital of America.
Sinead even shed a few tears as she sat with her new husband before they headed to a hotel for their wedding night.
She has only been dating Barry, who works as a counselor for people with addiction problems in Dublin, for three months.
Scrubbing up nice: The singer shed her usual tomboy image for this pretty strapless pink maxidress and chunky heels, but failed to cover her numerous tattoos
Happy tears: The singer got extremely emotional as she sat with her new husband after the ceremony was overHe replied after she wrote on her blog in September that she was 'sex-starved' and asked potential suitors to apply online.
'Barry sent me this wonderful email, which just took my heart away,' she told the Irish Independent before flying out from Heathrow to the U.S yesterday.
'It had to be him... I had no intention of getting married again but Barry was extremely persuasive. He proposed to me on every single date we have had since August. He is extremely persuasive -- and other unprintable things.'
The pair met up at a coffee shop and apparently 'talked for hours'.
Barry revealed the contents of the email to the paper.
We did it! The newly married couple snuggled up on a pink Cadillac
'At first I didn't know what she was doing, and then I realised she was playing hopscotch. It wasn't Sinead but a business woman in a suit and in her 30s, just having a bit of fun.
'I wondered why more women that age weren't doing the same thing? And it struck me that this was exactly what Sinead was doing with her search for love, having fun, and I told Sinead about this woman in my first email.'
He added: 'I love Sinead more than anyone I have ever met, or anybody I will ever meet. I am going to look after her.'
Sinead said she didn't want a big ceremony.
'I've been married before, but I've never had my dream wedding in Vegas. I wanted to do it there because it's casual, quick, not religious and, most of all, very romantic.
'People always complain, 'you never invited me to your wedding', but I prefer casual weddings. I'm so happy.'
Pucker up baby: The couple shared several passionate kisses for the cameras and stared into each other's eyes lovingly after being pronounced husband and wife
Igniting the flame: Sinead said Barry proposed on every single date they had until she said yesThe newlyweds have no time for a honeymoon as Sinead is due back in Dublin tomorrow to attend the aftershow party for a concert marking the 50th anniversary of Amnesty International.
The Little White Chapel has been the venue for several celebrity weddings, including that between Britney Spears and childhood friend Jason Alexander in 2004.
Other notable ceremonies include the wedding of Bruce Willis and Demi Moore in 1987, that between Frank Sinatra and Mia Farrow in 1966, and Judy Garland and Mark Herron in 1965.
Nice ride: The car is a tribute to Elvis' pink Cadillac. Some websites claim he married Priscilla at the chapel in 1967, but they actually tied the knot at the Aladdin Hotel
Still in the spotlight: The cameras were invited inside the chapel to capture every moment of the wedding
She wrote: 'With enormous joy myself and my beloved boyfriend Barry Herridge will be getting married tomorrow, December 8th 2011 at 'an un-disclosed location' in my absolute dream wedding ceremony.
'We will post a photo or two here on the site as soon as possible afterward. Very happy girl. : )'
Just wed: The newlyweds leave the chapel and head for their hotel
Keeping occupied: The lovebirds at their hotel afterwards where Barry played with an iPad
Wonder who is paying the bill? Sinead whipping out her credit card at the hotel
But Barry rang back into the show on Wednesday morning to reveal all to the host about the wedding.
Now that's taken care of: Sinead and Barry share a joke as the cameras snap away at their every move
Still going at it: The couple couldn't keep their hands off one another as they smooched in the hotel
'And it's Sinead's birthday tomorrow too. Congrats to them both. And Sinead's new album is sounding great too.'
The singer shocked the nation by writing a series of candid blog posts on her website earlier this year, detailing specific requirements she was looking for in a man.
She wrote in September that she was in 'desperate need of a very sweet sex-starved man,' but specified that they 'must be no younger than 44, must not be named Brian or Nigel, must be blind enough to think I'm gorgeous, has to be employed and he has to like his mother.'
