Tulisa was left devastated after someone keyed the word "s**t" into the bodywork of her £100,000 Audi last week.
This is the latest insult suffered by the former 'X Factor' judge, who has been subjected to a string of abuse since being arrested for allegedly facilitating the sale of £800 worth of Class A drugs.
A source told the Daily Star newspaper: "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.
"Between this latest incident and all the abuse she gets on Twitter, she's starting to feel like the whole world's against 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."
The 25-year-old star will answer to her police bail in late October following the drugs sting organised by The Sun newspaper in June. The former N-Dubz singer allegedly said she could arrange for cocaine and cannabis - "white sweets" and "green sweets" - to be delivered to an undercover reporter.
She said: "Half my phone book sells it. Of course I can get it for you. Half the guys I know are drug dealers. One's a massive cocaine dealer. He's my best friend.
"We talk in lingo. Like we know what. I can't call him and go, 'Have you got any?' I'll say, 'Hi, have you got any sweets?' ... And I'm referring to what he knows is what. Like we have a whole lingo."
