Beyoncé’s not used to missing a step — but with “Cowboy Carter” tour tickets struggling to sell, fans are saddling up with jokes … and she’s stuck taking the heat.

With her tour kicking off tonight at L.A.’s SoFi Stadium, there are still more than 3,800 tickets up for grabs — and resale prices have dropped to $20. Pretty wild, considering it’s Queen Bey we’re talking about … and she literally just snagged an Album of the Year Grammy for “Cowboy Carter”!

Bey seemed a little oblivious over the ticket sales … dropping an IG teaser Sunday showing off the venue with the caption, “SHE COMING” — but someone might wanna give her a heads-up that “NO ONE COMING.”

Dorit Kemsley won’t give her estranged husband PK the time of day … ignoring him while they separately attended their kid’s baseball game on the day after she filed for divorce.

Check out this video from the weekend showing how icy things are between Dorit and PK … she won’t even look his way as they sit in the stands of a Little League baseball field.

The tense standoff unfolded Saturday … less than 24 hours after Dorit beelined it to court and filed for divorce from PK following 10 years of marriage.

Dorit looks like she wants nothing to do with PK … who was spotted Thursday night at Cipriani’s in New York City, where he was making out with Shana Wall … an “Amazing Race” contestant who used to go out with Ryan Seacrest.

The reality TV star’s already shed her wedding ring, and she’s requesting spousal support from PK.

Travis Scott‘s carefully curated Cactus Jack-themed Coachella didn’t come without a price … the hip hop headliner cost the festival’s organizer $20,000 for squeezing out a few extra minutes!!!

A rep for the city of Indio tells TMZ Hip Hop that Goldenvoice will be charged $20,000 for one night of missing the curfew timeline, on Saturday, April 12, when Travis was on center stage.

It was the only fine issued for Goldenvoice across both Coachella weekends and Stagecoach festival, which went down on April 25 – 27.

Coachella Festival and Indio initiated their existing contract in 2013, which runs through 2050 … a move to give curfews more wiggle room than in past agreements.

The previous contract called for a midnight curfew on Fridays and Saturdays, and an 11 PM curfew on Sundays.

We’re told the fines are collected for Indio’s General Fund, which aids the city’s operating costs, including public works and the police and fire departments.

The rap megastar wasn’t slouching onstage … he started his set at 11:30 PM and premiered two new tracks, “Dumb” and “Kick Out” that could very well pop up on his upcoming label compilation “Jackboys 2” very soon.
