Adele may have a new celebrity bestie.
It's reported that she met up with Celine Dion before the Canadian star went on stage in London last night.
The Sun newspaper says that Celine then teased the crowd at her concert by saying she had always wanted to sing with someone - before performing a verse of Adele's hit Hello.
However it also says its source claims Adele would be too scared to perform with Celine, which we think is ridiculous because we would LOVE to see these two belting out a tune together!
