'A Star Is Born' Reunion! Bradley Cooper and Lady Gaga Praise Mark Ronson in Documentary Trailer

Bradley CooperandLady Gagaare praising the man behind their iconicA Star Is Bornduet.

Both stars appear in the official trailer for the upcoming YouTube documentaryHow To Be: Mark Ronson. The film explores the life of prolific music producer Mark Ronson, who wrote the hit song “Shallow” withLady Gaga, Andrew Wyatt and Anthony Rossomando. The foursome later picked up the Best Original Song Oscar for the tune earlier this year.

“Mark Ronson is…one of the greatest musicians and producers of our time,” Gaga says, with Cooper saying he’s “like a film nerd, but he’s the coolest guy there is.”

The documentary reunites Cooper and Gaga on screen a year afterA Star Is Bornhit theaters and cemented them as a powerhouse duo. The two later caused a frenzy withtheir intimate performance of “Shallow”at the 2019 Oscars ceremony.

“He has a huge and overwhelming connection to Gaga but whether it becomes a real love story in their lives for all the world to see is premature,” the source said.

And while the pair’s chemistry allowedA Star Is Bornto soar to great heights (see its eight Oscar nominations), therumors of a possible romance between themmight have played a role in Cooper’s split from ex-girlfriendIrina Shayk.

“The rumors about Bradley and Gaga having a love affair didn’t help especially with his constant travels [promoting the film],” said the source.

How to be: Mark Ronsonpremieres Oct. 12 on YouTube.
