Justin Bieber looks like a guy without a care, posing and smiling with fans today in New York.

Justin was on his way out of a radio station and even though people were asking questions about Mariah Yeater, he didn’t seem to be bothered one bit.

It makes sense considering Yeater’s looking more and more like a TOTAL FRAUD.

TMZ broke the story … Yeater dismissed her lawsuit against Biebs last week … and now, new text messages appear to show that she planned to hide any proof that her ex-BF is the REAL baby daddy.

Still no proof yet Mariah Yeater was anywhere near Justin Bieber around the time she got pregnant but what we can prove she was with her ex-boyfriend.

TMZ has obtained photos of Mariah and her ex-boyfriend Robbie Powell from last September. And she gave birth ten months later. It’s not exactly nine months, but it might be close enough.

As we first reported, Mariah texted friends after giving birth in July begging them to tell Robbie “how important it is for him to be in his son’s life.” She later asked her friends to please delete the texts and that she would give them money once she gets paid (by Justin).

And if the pics aren’t enough law enforcement sources tell us, Mariah and Robbie were questioned by police TOGETHER just last month in connection with some drug bust in San Diego.

Neither was arrested or charged with a crime — but it proves the two are still hanging out.

Four days after the drug bust, Mariah filed a paternity suit against Justin Bieber.

Forget about the DNA blood test. Conan’s peanuts explained how it really all went down that night Justin met Mariah Yeater.

Wow now they even have a video game of JB’s mama drama. Someone made a game out of the Mariah Yeater scandal. In the game you decide if JB is the daddy by throwing things at the window. Throwing baby bottles at him makes him the daddy. And throwing pregnancy testers at him makes him not the daddy.

Sound fun? NOT! Well it ain’t. But hey you can try it out yourself here.

The full Mariah Yeater interview will be on The Insider tonight. Make sure you watch and see what she has to say about that night. Whether she is telling the truth or not I actually feel sorry for her. Do you?

Justin Bieber will take a blood test in two weeks when he returns to the USA to prove he is not Mariah Yeater’s baby daddy  and after that, Justin and his team are going after her in court, sources directly connected with Justin told TMZ.

Justin is in Europe right now so he can’t take the test until he returns but he is determined to put an stop to what he says is a bogus scandal.

Our sources say Justin’s lawyer, Howard Weitzman, contacted Yeater’s attorneys Friday and said the blood test will happen no matter what. We’re told Justin and his team are so serious they directed Weitzman to find a lab to do the test and he has already selected one.

Once the test shows Justin is not the father, Justin and his team will sue her. We’re told Yeater’s lawyers appeared “nervous” when they heard the news. This may explain why Yeater’s lawyers went underground yesterday and did not return TMZ’s calls.

Sources say Bieber and his team think it’s important to file a lawsuit against Yeater to show there are consequences when someone makes up fake, hurtful allegations against a celebrity.
