With the news dropping recently that Black Panther's "All The Stars" and A Star Is Born's "Shallow" would be the only nominated songs performed at the 91st Academy Awards, Lady Gaga and Bradley Cooper chose to get a bit of impromptu practice in.
Going by the crowd reaction, you've got to imagine that a possible tour has been floated for Bradley Cooper and Lady Gaga.
While Cooper sang, Gaga knelt beside him and put her arms on his leg.

Huawei also launched the 5G CPR Pro, a 5G router that uses wifi 6 technology to claim speeds of nearly 5 Gbps. He also said a "blanket ban" on the Chinese firm's equipment would slow Vodafone's rollout of 5G networks.
If you attend a Lady Gaga performance, you should no doubt be ready for uninmagineable surprises. Lady Gaga, who co-wrote the song, played the piano as she belted out the song beside Cooper.
The pair are expected to reunite to perform the song at the Academy Awards ceremony on February 25 (New Zealand time). Much to the crowd's delight, Bradley threw in a little air guitar as his co-star finished up the song with its famous dramatic ending.
