I'll translate an important part from this interview
Pqpmag ask: why she isn't an angel. it's her choice or is a problem with contracts of other brands ?
Ana BB says : it was her choice. a while ago they offered her a contrac but L'oreal also offered her contract at the same time and she couldn't have both so she decided to sign with L'oreal cause the contrac (money ) was better.
if you want my opinion i think it was really stupid of her. cause VS ALMOST always starts paying a low salary for their angels. but when they see the public loves them their salary hit the millions a year. see what happened to Adri and Ale? it could be happening to Ana now. too sad ! i would love her on VS
