Ulrich addressed "a couple of things" in a comment on his Instagram account, including debunking a rumor that he's dating co-star Morgan after it appeared she was living at his home while she was looking for a new place. Ulrich also wrote: "I have had an internet stalker/troll for far too long now. She has cost me thousands of dollars and lawyer's fees and time spent with law enforcement to try  to stop her behavior. She has even threatened to send people to my house."
