EXCLUSIVE: Things are progressing toward Lady Gaga teaming with Bradley Cooper in the Warner Bros remake of A Star Is Born. Deadline revealed this pairing back on May 2, that this was the reason why paparazzi got pics of Cooper, taking a motorcycle ride to a restaurant for dinner, with none other than Lady Gaga hanging on to him for dear life. The update here is they tested and the studio loved the results. I can tell you reliably that she was the one actress he went to, after things didn’t work out with Beyonce, and they sparked to one another. Negotiations are expected to happen shortly on a pic that Cooper is producing with Todd Phillips through their Joint Effort banner, and Bill Gerber, who has been working on this remake for a long time with a draft by Will Fetters that is being reworked with Cooper.

A Star Is Born marks Cooper’s directorial debut at Warner Bros. Deadline revealed over a year ago that Cooper had targeted this for his first behind-the-camera turn, and in February we reported the film had been chosen for tax credits from the state of California, so it’s real. Beyonce was once circling the ingénue (played by Barbra Streisand last time around), but that cooled. That opens the door for Lady Gaga, whose participation guarantees a killer soundtrack and who won a Golden Globe acting in front of a camera in Ryan Murphy’s American Horror Story series. So just watch these two turn up together here and there as Cooper gets serious about making this film. He’s got offers in other places to make his directing debut, and it’s a priority for him after learning a lot at the side of Clint Eastwood in the making of American Sniper. Cooper produced that film, which was brought in at a reasonable budget. A Star Is Born will probably cost $30 million.

Cooper and Gaga are repped by CAA.
