Poor Farrah Abraham.
The Teen Mom OG star paid homage to her late ex-boyfriend, Derek Underwood on Twitter after a fan tagged her in this gorgeous collage.
"@F1abraham this melt my heart," the user wrote alongside a sad emoji.
Farrah replied with, "Love this."
Derek is the father of the MTV star's daughter, Sophia, but was tragically killed in a car accident before she was born. He is survived by his family — who we sometimes see on the TV show, and Farrah also makes it a point to take her seven-year-old to visit his grave.
