I mean, I don't know 100% but I believe their contracts make them exclusive to PINK. I'm not sure if that was the case with Behati, but it was definitely what happened with Elsa. I'm positive Rachel is out(no accolades at the VSFS, and she's missed two large on location shoots for PINK that Zuri and Grace have both been on) so it's hard to say what the length of Grace's contract could be. Rachel only did two years, but I don't know if that was just the length of her contract, or if she was actually dropped from the brand and they bought out the remainder of her contract.
