Orlando Bloom is reportedly feeling the heat — and not just from the sun.

The Pirates of the Caribbean star was said to be utterly embarrassed by Katy Perry’s controversial space flight aboard Jeff Bezos’ Blue Origin rocket.

As the couple’s relationship shows signs of serious strain, insiders reveal that an explosive argument over the space trip might be the latest crack in their rocky romance.

According to the Daily Mail, Bloom blasted Perry’s Blue Origin flight as “embarrassing” and “cringeworthy” during a heated exchange.

The actor reportedly told her, “the whole thing looked ridiculous.”

“It hurt her feelings. Of course, she was hurt. Imagine going to space — motherf--king space — and your partner isn’t impressed,” a source told the outlet.

The “Firework” singer had reportedly hoped her fiancé would be more supportive.

Adding fuel to the fire, Perry is reportedly upset that Bloom will attend Bezos’ wedding to Lauren Sánchez without her, since she is currently on tour.

“He complains about her going to space, and then wants to go to the wedding of the people who made it possible for her to do this in the first place,” the insider said.

“They’re already spiraling, and now the wedding is another thing they have to fight about," they added.

The breakdown of their decade-long relationship — which included a 2019 engagement — is reportedly tied to two major factors: Perry’s latest album 143 and her Lifetimes world tour.

According to insiders, their romance has been “breaking down” in recent months, with one insider bluntly stating they are “pretty much done.”

The source added that “it isn’t looking good” and they “don’t really see them being able to turn things around.”
