When iwrestledabearonce announced they are working with a fill-in vocalist, Courtney LaPlante to replace Krysta Cameron while she was on pregnancy leave, it was pretty obvious to me that Krysta wouldn't be coming back. She's not going to tour with a kid inside of her, and I can't see her wanting to tour with a kid waiting for her at home either.
Now, the band pretty much confirms she is out of the band. In this interview, their bassist Ricky said "I’m going to say she’s permanently gone." with drummer Mike Montgomery adding "Fingers crossed though [that she'll return]."
Metal is all fun and games until you get preggers, then life hits you in the face with reality and you have to start thinking about the future. You can't raise a kid being in iwrestledabearonce. The band has not committed to Courtney LaPlante as a full-time vocalist either, saying they will reassess the band at the end of their run on the Warped Tour.
