Lady Gaga and Bradley Cooper shippers would be delighted to know that the two actors have reunited. However, their reunion has nothing to do with their alleged relationship.

Gaga and Cooper are featured in the upcoming documentary about Mark Ronson, a British music producer. In the teaser released via YouTube for “How To Be: Mark Ronson,” Gaga and Cooper both share their thoughts about the producer.

The “Poker Face” singer dubbed Ronson as one of the greatest musicians and producers today. Cooper echoed the same sentiments about Ronson.

Gaga has worked with Ronson on multiple occasions. They collaborated on her 2016 album “Joanne.” The singer also cowrote the popular song “Shallow” from “A Star Is Born” with Ronson and two other artists.

Other artists featured in the upcoming documentary include Miley Cyrus, the late Amy Winehouse, Bruno Mars, Sean Lennon and more — who all have worked with Ronson. The documentary will be available on YouTube on Oct. 12.

Meanwhile, even though Gaga and Cooper’s most recent reunion had nothing to do with rumors of their alleged relationship, it’s still a welcome sight to see them on screen together. After the costars appeared in “A Star Is Born,” rumors have been ripe that they have forged a relationship with each other.

Just last month, rumors swirled that Gaga and Cooper decided to end their so-called relationship because the latter couldn’t handle the media attention that they received. Days later, a tabloid claimed that Gaga was heartbroken over the end of her budding romance with Cooper.

The singer has reportedly been telling her closest friends that Cooper broke her heart. “Gaga feels Bradley led her on because he was giving off all the signs that they’d become an item once he was single,” a source said.

And one of the most shocking claims about the costar’s alleged romance was the fact that Cooper almost proposed to Gaga before he decided to end things with her. A tabloid said that Cooper was already thinking of buying Gaga a ring when he suddenly realized that he needed to date more women before he could settle down. But according to rumor-debunking site Gossip Cop, none of these claims are true.
