Aaron Carter's loved ones are processing their grief after the loss of the musician-actor.
In the wake of the LØVË artist's sudden death at age 34 on Saturday, his on-and-off fiancée Melanie Martin, with whom he shares 11-month-old son Prince, expressed her heartbreak through a brief and tearful TikTok video.
In the two-second clip, Martin can be seen sobbing from what appears to be the driver's seat of a moving car, prompting the app to provide a disclaimer: "Participating in this activity could result in you or others getting hurt."
She also shared a throwback recording of a TikTok Live, in which Carter showed off some silly dance moves for his followers. "Forever posting," Martin wrote in the caption.

A spokesperson for the Los Angeles County Sheriff's Department told PEOPLE a body was discovered just before 11 a.m. local time, but police did not officially identify the victim.
Police sources tell PEOPLE the star was found by a house sitter in his bathtub, and that there were prescription pills and drug paraphernalia in his bedroom. Though a cause of death has not yet been determined, the police sources believe he lost consciousness and drowned.
Carter revealed a permanent expression of his love for Martin in March 2020, debuting a "Melanie" face tattoo over his right eyebrow, two months after they made their relationship Instagram official.
"She loves me she loves me not, she woke me up from napping but I'm not complaining," he captioned their first photo together that January.
The pair announced their engagement in June 2020, and they welcomed baby boy Prince last November. Carter previously opened up to PEOPLE about his excitement over potentially starting a family back in 2018.
"I'm going to be a good father. I know it," Carter said at the time. "I want lots of kids, lots of stability, lots of happiness and laughter and learning and having fun. It's going to be good."
The on-and-off couple called off their engagement a week after welcoming Prince, and then got back together in December 2021, before breaking up again in February 2022. Their relationship status at the time of Carter's death is unclear.
