A source told The Sun about Selena being pushed aside by the makeup brand:
It was a decent payday for Selena and she was Almay’s first choice. But once they got wind of her fortnight in rehab, they got cold feet. She had shot videos and all the press photos by the time they pulled the plug.
Almay instead hired Carrie Underwood.
What a bummer for Selena! Hopefully she gets to work with the company again in the future!
