Britney Spears says she married her childhood friend Jason Alexander because she was “very drunk” and “bored.”

In her new memoir, “The Woman In Me,” Spears writes about her infamous 55-hour marriage to Alexander in 2004 during a trip to Las Vegas.

Spears says that during the trip, she “wound up in bed” with Alexander, whom she doesn’t name in the memoir.

The “Gimme More” singer says that on the third night that they were together, the pair got super drunk in their hotel room and decided to go to A Little White Wedding Chapel, a venue that has been used for several celebrity elopements.

“People have asked me if I loved him. To be clear: he and I were not in love,” Spears writes. “I was just honestly very drunk — and probably, in a more general sense at that time in my life, very bored.”

Spears then recalls her parents flying to Vegas the next day.

“They showed up and stared at me with these eyes of such fury. I looked around. ‘What happened last night?’ I asked. ‘Did I kill someone?'” Spears writes. “‘You got married!’ they said, as if that might be somehow worse. ‘We were just having fun,’ I said. But my mom and dad took it so seriously. ‘We have to get this annulled,’ they said.”

The pop star continues: “They made way too big of a deal out of innocent fun… I thought a goof-around Vegas wedding was something people might do as a joke. Then my family came and acted like I’d started World War III.”

The singer says her parents almost immediately arranged for the marriage to be annulled.

“We signed all the documents they told us to sign. The marriage lasted 55 hours. I thought it was strange they got so involved so quickly and so decisively — without my even having time to quite regret what I’d done,” Spears writes.

Alexander and Spears appear to have grown apart since their impromptu wedding.

Last year, Alexander was arrested after he livestreamed himself crashing Spears’ wedding to Sam Asghari. The Associated Press reported that he was sentenced to 64 days in jail.

“The Woman In Me” is available to buy at Amazon, Bookshop, and other bookstores.
