Britney Spears’ ex-husband Jason Alexander, is clapping back at her claim she only married him because she was drunk and bored … instead, he insists it was true, sober love, TMZ reports.

Britney Spears’ ex-husband Jason Alexander who was married to Britney for a whopping 55 hours in 2004 before getting an annulment, says fans shouldn’t believe a word Britney says about their marriage in her new memoir, according to TMZ.

In “The Woman In Me,” Britney says she and Jason “got sh**faced” before tying the knot early one morning in Las Vegas back in January ’04 … adding, “People have asked me if I loved him. To be clear: he and I were not in love”

Britney also writes, “I was just honestly very drunk — and probably, in a more general sense at that time in my life, very bored.”

Britney Spears’ ex-husband Jason Alexander slammed the claims, because they were absolutely in love and weren’t boozing, which is exactly how their wedding officiant described the couple in a previous interview.

According to the report by TMZ, Jason says they have been friends since childhood, and he still cares for and loves her, however, he adds, that he did never buy her memoir, and would only accept a copy if it was signed and, even then, he admits he did probably “sell it to the highest bidder.”

Britney’s revealed a ton of bombshells in the book and Jason says, in his opinion, Britney’s abortion from her pregnancy with Justin Timberlake was a “horrible decision.”

He also weighed in on Britney’s rationale for her nude photo posts … saying he sees it as “childish behaviour” from a mother, but he believes Justin cheated, and then broke up with Brit in response to her cheating.
