Jackson and Ally have reunited. In what appeared to be the beginning of a running campaign for an Oscars performance slot, Bradley Cooper joined Lady Gaga on stage during one of her shows in Vegas. Together, the duo sang Shallow, the track they made famous in their award-winning film A Star Is Born. And how the crowd roared.

Watch it now. You can see Gaga kneeling down, almost bowing to Cooper, as he begins the song with “Tell me something, Girl…”

Shallow won Best Original Song at both the Golden Globes and the Critics Choice Awards this month (Gaga also took home Best Actress at the latter.) Cooper and Gaga are both nominated for Best Actor and Best Actress at the Academy Awards. The film itself is also nominated for Best Picture.

It has not been confirmed whether Cooper rand Gaga will perform Shallow at the ceremony on February 25. Upon the nomination announcements last week, Gaga told the LA Times it would be an honour to perform the song at such an event.

Gaga must have been on a red-eye straight out of Vegas as she is currently walking the red carpet at the 2019 Screen Actors Guild Awards in Los Angeles.
