The 24-year-old has been going through a rough time with series of negative publicity coming to her. It includes leak of her sex tape, undercover sting operation and being fired from British reality show "The X Factor".
"Tulisa thinks she knows who was behind the damage to her car. As soon as she found out, she had it towed away to get it sorted out, but it has upset her," dailystar.co.uk quoted a source as saying.
"Between this latest incident and all the abuse she gets on Twitter, she's starting to feel like the whole world's against her," the source added.
The singer has so far taken everything in good spirit, but this incident has depressed her.
"Tulisa prides herself on being good at coping with all the negative attention, but it's a different ball game when people are starting to mess with her private property," a source said.
