Her dreams of a perfect party went up in smoke.

A UK mother’s gender-reveal party evoked the scene of a riot after pink smoke bombs filled the air — forcing the guests to flee the scene. A now-viral video of the candy-colored catastrophe has racked up nearly 1 million views on TikTok as of Wednesday afternoon.

“The smoke bombs threw out a lot more smoke than I thought, it just really shocked us all,” Mandy Morgan-Smith, 22, who was 17 weeks pregnant, told Kennedy News of the mommy mishap.

The mother of one, from Cardiff, Wales, bought two pink smoke bombs and two blue ones for around $45, because she wanted to go “all out” for her sex-unveiling soiree.

Little did she know that the canisters would emit such volcanic levels of smoke.

The 30-second video, shot by Mandy’s mother, Tammy, on May 7, begins innocently enough, filming the expectant mother activating the devices with her 3-year-old daughter, Willow-Rae Morgan-Smith. Pink smoke shoots out, signifying that she’s having a girl.

Things quickly take a turn, however, after the smoke doesn’t stop billowing, filling the air with a thick pink miasma, and obscuring the vision of the guests.

“I can’t breathe,” screams Tammy, before ordering McCalley Morgan-Smith, 25, to remove his 1-year-old daughter from the trampoline and indoors, away from the fuchsia fog.

The dramatic clip ends with the guests scrambling for the house to escape the fumes like a catastrophic color run.

Mandy painted the scene: “Everything went to plan at first. I was over the moon with it being a girl, but then straight away I was thinking, ‘Oh my god, I can’t breathe,’ ” the distraught mom described. “It just wouldn’t stop, it got worse and worse. We thought it would have died down. It filled up our garden, the neighbor’s garden, then right to the third floor of our house.”

She added, “My mum was thinking about all the kids and making sure they were alright, and I just grabbed my daughter and ran in[side].”

Mandy said the smoke itself had a “weird, strong smell” that was “not nice . . . It probably wasn’t good to inhale that much smoke, there was so much of it, but luckily nobody was really struggling,” she described.

Fortunately, no one appeared to be harmed during the fiasco, and the future mother-of-two is taking the smokeshow in stride.

“You’ve just got to make a joke about it. It’s hilarious, the video is great,” mused Mandy. “It was definitely more eventful than having a colored balloon.”

She summed up the incendiary incident like this: “It’s such a great memory, and it’s great to make everyone laugh. I can’t wait to show my future daughter that she was causing a riot before she was born.”

Needless to say, many TikTok viewers were amused by how the party bit the dust.

“The way it just didnt stop,” exclaimed one gawker, while another quipped, “Why am I coughing like I was there.”

One sarcastic spectator snarked, “Do you think it’s a girl?”

Excessive smoke is far from the worst thing to happen at gender-reveal parties, which have seen every color of calamity from forest fires to fatal explosions.
