Paris Hilton reportedly lost two cellphones on a flight to the Philippines for a visit to promote a residential resort project.
TV footage shows the hotel heiress looking upset and going through her bag at the Manila airport, according to the Associated Press. Airport officials reportedly are investigating. Hilton has not commented on the incident.
This isn't the first time the 30-year-old had issues with the security of her cellphone. In 2005, hackers got into Hilton's cellphone and posted the private phone numbers of her celebrity friends on the Internet.
Hilton, who stars in the reality TV show, "The World According to Paris," is in Manila to promote her latest real estate venture. She has partnered with Century Properties to design an amenity at the Azure Urban Resort Residences.
"So excited for this project in the Philippines. It's going to be beautiful, incredible and so much fun!" she tweeted.
