Family and friends are hoping to find Camela Leierth-Segura, a musician who they say vanished nearly seven weeks ago.

According to her missing persons page located on the California Department of Justice website, the 48-year-old, who co-wrote Katy Perry's song "Walking on Air," has not been heard from since June 29. 

Her friends told local outlet KABC that her 2010 silver Ford Fusion was last seen in Beverly Hills and that her 19-year-old cat Morris is also missing.

"I'd like to think nothing bad happened," Leierth-Segura's friend Cecilia Foss told the outlet. "But do I think something bad happened? Yeah."

The musician's landlord in Beverly Hills told KABC that she was evicted before her disappearance. Neighbors noted to the outlet that there are now dead plants on her balcony and a "For Rent" sign located outside.

Her friend Liz Montgomery explained to the publication that Leierth-Segura's family, who live in Sweden, reached out for assistance after not hearing from her for several weeks. Montgomery herself also issued a public plea to help locate the missing model.

"We are desperately seeking information on the whereabouts of our dear friend, and sister, Camela Leierth, who may also be using the name Camela Leierth Segura," Montgomery wrote in an Aug. 9 Instagram post. "Camela has been missing since June 29th, and her last known contact was in Beverly Hills, California."

She continued, "We are extremely worried about her safety, and despite our best efforts, the local authorities have not been able to locate her. She means the world to us and time is of the essence. Her family in Sweden is pleading for your assistance."

Montgomery concluded her emotional plea with the hope that her friend will be brought home safely, adding, "Thank you for your support and assistance in this critical matter."

E! News has reached out to the Beverly Hills Police Department for updates on this case and has not heard back.
