The fashion designer is yet to be married. However, she was previously engaged to Paul Michael. Paul and Amanda began dating in late 2019. On 2020's Valentine's Day, the former actress announced their engagement in a now-deleted post on her Instagram page.
She shared a photo of her silver ring and his gold band, referring to Paul as the love of her life. Michael disclosed to Page Six on March 2023 that the Bynes had turned wild as she had stopped taking her medication before being placed on a psychiatric hold. He stated:
She got off her meds, and she's still off her meds. She's wild.
