Eminem adopted Alaina Marie in the 2000s. Kim's twin sister, Dawn, had a substance addiction, limiting her ability to take care of her kid. Eminem took Alaina (who was born in 1993) under his wing. She is frequently described as his "forgotten daughter," as many fans aren't aware of her presence in the rapper's life. Alaina's mom, Dawn, passed away in 2016, after periods spent without having a home. Some claim the cause of death was heroin overdose.

"My niece has been a part of my life ever since she was born," Eminem told Rolling Stone in 2004, via The Hollywood Reporter. "Me and Kim pretty much had her, and she’d live with us wherever we were at."

Alaina made public her engagement with Matt Moeller on Dec. 14, 2021. They got married in Detroit in June 2023.

According to Instagram, she is passionate about body positivity and mental health, and runs a book club.
