Mariah Carey torches $250K dress for James Packer wedding

Well, that relationship went up in flames.

Mariah Carey used the music video for her song “I Don’t” to send a heated message to her ex-fiancé, Australian billionaire businessman James Packer — by setting fire to the wedding dress she never wore.

In the video, the singer is seen dancing around the $250,000 Valentino gown, which she had shown off on an episode of her ­reality show “Mariah’s World,” as it burns.

TMZ reported that the video was shot at the Calabasas, Calif., home Carey and Packer shared before breaking up last October, shortly before the couple’s Bora Bora wedding ceremony was set to take place.

The song contains the lyrics: “I’m tired of cryin’, no more tears, pity party of the year.”

But the party didn’t last too long. Carey is now reportedly dating one of her backup dancers, Bryan Tanaka.

The Packer union would have Mariah’s third.

At her first wedding, to former Sony Music boss Tommy Mottola, Carey wore a $25,000 Vera Wang dress that was reportedly inspired by Princess Diana’s bridal gown.

The couple lasted for four years utnil they split in 1997.

For Carey’s second wedding, in 2008, she donned a sleek Nile Cmylo slip dress to pledge her everlasting love to “America’s Got Talent” host Nick Cannon — then wore a new gown each time the couple renewed their vows, annually, over the next five years.(Among the over-the-top places they recited their vows: the Eiffel Tower and Disney World.)

Carey and Cannon, the parents of 5-year-old twins Monroe and Moroccan, filed for divorce in 2014 but the split became final just last year.

There’s no word on whether Carey has saved or torched her previous wedding gowns.
