She saw Carrie in the gym & said she had no idea her face had been injured. But Carrie sounds like she's self conscious!
Carrie sent a message out to fans saying she hurt more than her wrist in her fall, that she actually had to get 40-50 stitches in her face, and she "may look a little different". See that statement HERE.
However, a fan posted this photo taken in mid December after Carrie's accident saying she looks amazing!
Maybe the stitches were on the other side of her face not shown in the picture, or maybe Carrie is just feeling really insecure about a new scar. Either way, it looks like her fans stand behind her no matter what!
