Irish firebrand Sinead O'Connor played one of her own songs at her Las Vegas wedding on Thursday, her 45th birthday.
No word on if it was "Nothing Compares 2 U."
Known for courting controversy -- Frank Sinatra threatened to "kick her in the ass" -- an "absolutely adorable" O'Connor got hitched in the back seat of a pink Cadillac convertible in the Tunnel of Love drive-through at Little White Wedding Chapel on Las Vegas Boulevard.
Her fourth husband is Barry Herridge, 38, an Irish therapist who contacted O'Connor in August after she let it be known on her blog that she was husband-hunting and in "desperate need of a very sweet sex-starved man."
Officiating was chapel owner Charolette Richards, who said she comped the wedding, including the pink Cadillac convertible package, which usually goes for $325 to $599.
"She brought her own CD player," said Richards. "It was her singing. She was absolutely adorable, very sweet."
O'Connor's incendiary political statements made her one of the most reviled celebrities of her era. In 1992, she insulted Pope John Paul II by ripping apart a photo of him during a "Saturday Night Live" appearance.
A year earlier, O'Connor enraged Sinatra when she refused to allow the national anthem to be played before her concert at the Garden State Arts Center in New Jersey.
Sinatra, who performed at the Center the next night, said he wanted to "kick her in the ass."
There's a delicious irony to the O'Connor-Sinatra connection.
Richards, who has been officiating weddings here for 53 years, married Sinatra and actress Mia Farrow at the Dunes on July 18, 1964, the year O'Connor was born.
O'Connor's wedding was one of the chapel's biggest "name" nuptials since Britney Spears, on a lark, got married on Jan. 3, 2004. The marriage was annulled 55 hours later.
