Katy Perry's rocky Lifetimes Tour hit yet another snag when she tripped and fell onstage during a show in Phoenix, Arizona.

Amid reports of sluggish ticket sales, the tour began inauspiciously this April with a Mexico City concert that left fans roasting the 40-year-old for her 'mom moves.'

As she jetted around the world for her gigs, her personal life made headlines with news that she had split from her fiancé Orlando Bloom, who attended Jeff Bezos and Lauren Sanchez's wedding solo as Katy performed in Australia.

Now, in fan footage circulating on TikTok, the California Gurls hitmaker was seen running onstage before stumbling and falling painfully on her front.

She quickly recovered, drawing herself up to her knees and managing an improvised little dance that consisted of her jerkily pumping her fists up and down. 

Online observers shared their reactions, as one wrote: 'on stage she acts like a toddler running around at a wedding' and another wondered: 'Who is paying for this.'

A third remarked that 'her tripping is the least embarrassing part of this video,' while a fourth said: 'If I had free tickets I still don’t think I’d go.'

One waggish TikTok user took aim at Katy's controversial all-female space flight, quipping: 'She’s getting used to earths gravity again guys, don’t make fun of her.'

Others wrote: 'Not a single one of her songs warrants any of this,' 'You couldn’t pay me enough to see her in concert!!,' 'The humiliation continues…,' 'Her career in 2 seconds,' and: 'They paid to watch her "baby shark."'

Exactly one week after the Phoenix mishap, Katy left fans terrified by nearly falling out of the air during a performance in San Francisco.

Fans were left panicked as they captured the heart-stopping moment when she belted out her hit song Roar while soaring through the sky on a mechanical butterfly.

Taking to Instagram the following day, Katy found the humor in the situation as she shared a series of snaps poking fun at the incident.

Captioning a set of photos that showed the contrast of the day, she wrote: 'How the LA show started ➡️ how the LA show ended.'

The first snap showed Katy relaxing in a bathtub, before cutting to some behind-the-scenes snaps of the show.

It then switched to footage of Katy plunging downwards on the flying stage prop above the audience, followed by a clip of her walking out of the arena in her dressing gown, looking noticeably shaken.

Katy also shared a snap on her Stories of the fall, with the caption: 'Goodnight San Francisco.' 

On Friday, Katy who was dressed in a sparkling crop top and hot pants, initially looked at ease as she glided over the crowds at the Chase Center while singing her track amid her The Lifetimes Tour. 

However, things took a turn for the worst as she suddenly plunged downwards as the flying stage prop appeared to malfunction. 

The US songstress, who was strapped in, was seen looking horrified as she grabbed onto mechanical insect and attempted to steady herself, before looking upwards to see what was wrong. 

Amid the incident, Katy stopped singing as she tried to compose herself, before she then continued with her performance.

The large flying prop appeared to slow down significantly as it made its way across the arena.

MailOnline have contacted Katy's reps for comment. 

Taking to X (formerly known as Twitter), fans were quick to share the shock at the moment, with many comparing it to a similar incident that Beyoncé suffered last month.

The Halo singer, 43, almost fell out of her flying car prop which had tilted forward while she performed in Houston amid her Cowboy Carter tour. 

Fans wrote: 'First beyonce and now katy perry, next its gonna be usher being sent into outer orbit.'x

'First Beyoncé now Katy Perry'

'The professionalism here is beyond insane like that could've easily cost your life but Katy didn't panic and she kept the show going.... Katy Perry is hands down one of the best performers of our generation.'

'sorry katy perry is such a pro, i would have just cried and sh*t myself atm.'

'Katy Perry almost fell ON TOP of me while flying on that butterfly. This concert is WILD.' 

Katy's dangerous moment comes after she was left overwhelmed with emotion during her Lifetimes tour stop in Los Angeles on Tuesday night.

The pop star alluded to her recent breakup with now-ex-fiancé Orlando Bloom while obliging fans' request for her to sing her heartbreak ballad Not Like the Movies.

During the show the show in the city's Inglewood neighborhood, she asked the audience: 'You're gonna make me sing this song in this time in my life? OK, we'll do it! Because you voted for it.'

According to an account from People, she continued, 'I let you choose the song tonight because I like to pick an album for every country that I go to and for the USA, I picked Teenage Dream because USA, you could be a teenage dream, baby. You better get it together. I'll always have that feeling for you.'

Per the outlet, she candidly added, 'This next song I wrote in my 20s … after my first divorce,' before promising she would 'try and hold my composure while I sing it a week before my period.'

Earlier in the day she had snubbed Bloom in her Instagram post promoting the concert.  

She listed everyone who would be in attendance for the show in her native Los Angeles, and missing from the special guests was the 48-year-old actor.

Perry's caption to her 203 million followers began, 'HOMETOWN SHOW AT THE FORUM TONIGHT‼️'

Showing her sense of humor, she then added, 'Ecstatic to play a show for ALL the Angelenos including my best friends, my business partners, mom, dad, my ear nose and throat doctor, my dog groomer, my MDMA therapist, my acupuncturist, my manicurist, the teacher from the yoga class I went to in 2015, the uber eats guy that that delivered my brisket breakfast burrito this morning from Dialog Cafe and all the friends that are friends with someone that knows Tamra.' 

While Orlando wasn't present for the performance, his ex-wife Miranda Kerr was in attendance. 

Perry and Bloom confirmed their breakup this month, after swirling speculation about their relationship status.

The pair began dating in 2016 and got engaged on Valentine's Day 2019, before welcoming their four-year-old daughter Daisy Dove in August 2020. Bloom is also dad to 14-year-old son Flynn, whom he shares with Kerr.

Representatives for the pair told DailyMail.com that 'Orlando and Katy have been shifting their relationship over the past many months to focus on co-parenting. They will continue to be seen together as a family, as their shared priority is - and always will be - raising their daughter with love, stability, and mutual respect.'

The split was optically cemented when Orlando attended Jeff Bezos and Lauren Sanchez's star-studded Venice wedding alone.
