I feel sorry for any woman who went through that. However, the timing of such admission is a bit suss. Someone is clearly after that third season and I can't even be mad at that. There might be some speculation like with Kelly Rowland's admission in regards to her domestic abuse from a past relationship (her abuser still remains unidentified). Christina says the abuse happened when she was 18, so it couldn't have been any of the famous men she hooked up with in her career. Her music career hadn't even kicked off yet at the time. She supposedly date Demi Lovato's boyfriend Wilmer Valderrama at around that time but it would be unfair to point fingers. At the end of the day, it could have been anyone.
