The album features guest appearances from DaBaby, Future, Halsey, Meek Mill, Lil Baby, Ozzy Osbourne, Travis Scott, SZA, Swae Lee, and Young Thug.

The production was handled mainly by Louis Bell, with contributions by Andrew Watt, BloodPop, Brian Lee, Carter Lang, DJ Dahi, Emile Haynie, Frank Dukes, and Malone himself, among others.

The album also includes the Billboard Hot 100 number-one single, "Sunflower", a collaboration with American rapper Swae Lee, from the Spider-Man: Into the Spider-Verse soundtrack.

[3] That November, Malone stated that he was "trying to put out a new body of work" before the end of the year,[4] but only released the single "Wow" in that time.

[5] On July 28, 2019, Malone shared that he had finished recording his upcoming third studio album,[6] describing it as "pretty goddamn out of sight".

[10] "Take What You Want" featuring Ozzy Osbourne and Travis Scott, was sent to contemporary hit radio on October 15, 2019, as the album's sixth single.

[19] To further promote the album, Post announced the Runaway Tour with Swae Lee and Tyla Yaweh joining as the opening acts.

[31] Neil Z. Yeung of AllMusic saying "More well-executed than his previous releases and undeniably catchy, Hollywood's Bleeding is a huge step forward for the guarded superstar, one that doesn't sacrifice the essential elements that made him such a surprise hitmaker, and pushes him even further into the pop-savvy landscape where he belongs".

[24] Writing for Los Angeles Times, Mikael Wood stated, "Unlike Stoney and Beerbongs & Bentleys, this album feels composed of discrete stylistic exercises; no longer is he boiling down rap and rock and a little bit of country into a kind of smearable paste".

[32] Rolling Stone's critic Nick Catucci said, "Post Malone curates as much as he creates, and there's not a misplaced feature among the 10 spread across seven of these tracks".

[29] Dan Weiss of Consequence wrote, "Hollywood's Bleeding is immediately Post Malone's most listenable work and may well be the catchiest album you hear in 2019, and that includes Taylor Swift".
