First of all, CONGRATS! to Lauren Alaina for making it to the Dancing With The Stars finale!
It's not clear if any of that happened while they were dating, but if the allegations are true, then you have to think the answer is yes.
Anyway, ET asked her about him at Monday's Dancing with the Stars. She said,
"A breakup is always hard, but I've just been really focused on myself and dancing each week and doing my best."
Asked if John has reached out to her, she said,
"I have not talked to him recently. No. But I wish him and everyone in his story the best. All I want to do is the right steps on that dance floor every Monday night."
Lauren and her DWTS partner Gleb Savchenko advanced to the finale on Monday.
