Glaser admits to feeling jealous of Swift, writing, "I was probably 'feeling fat' that day and was jealous."
The apology continues, making reference to Swift's model squad,, "And I was only bothered by her model friends because I'd like to be her friend and I am not a model."
Although the documentary does not go too far into the details of Swift's eating disorder, it features several clips of her at what looks to be her skinniest.
In addition, the singer mentions how her relationship with food affected her ability to perform, saying that she felt "like I was going to pass out at the end of a show, or in the middle of it."
In response to Glaser's heartfelt apology, Swift left the comedian a sweet comment, forgiving her and "sending a massive hug."
