Heather Morris is apologizing to anyone who felt triggered by the recent comments she made about her late Glee co-star Mark Salling. After someone placed a vomit face emoji over Mark‘s face in a tweet about Glee, Heather spoke out to defend the memory of Mark and said it’s “incredibly tough” to act like his death is “invisible.” Before he committed suicide in January 2018, Mark pleaded guilty to possession of child pornography.
