Wait, she's doing BRIT so I'd not be surprised the first dates are postponed.
Or Travis is being replaced
Don't get too excited for a boost, cause Ellen rarely boost singles/albums, plus it's just an interview
The BRITs are like 2 days before the tour stars, it's not an issue.
Also, ELLEN sometimes gives boost. Troye Sivan recently got a pretty decent boost from ELLEN. Also Ellen has always been good exposure, and it will have people talking.
