Justin Bieber wants justice in paternity case

First we assured you that it seemed very unlikely Justin Bieber was the father of Mariah Yeater’s 3-month-old baby.

Now we can tell you that not only is the pop superstar going to take a DNA test to prove it – his high-profile posse of lawyers is also planning to file a huge lawsuit against Yeater, once Bieber has returned from the MTV Europe Music Awards in Belfast.

“It’s not that Justin or his attorneys expect to get a dime out of Yeater – she doesn’t really have any money – it’s just to send a message to people who might think about trying to pull a stunt like this on a famous celebrity in the future,” said a close Bieber buddy Sunday.

†Meanwhile, don’t believe those stories that Selena Gomez dumped Bieber over that alleged baby-fathering tale.

The couple still are very much together, but Gomez reportedly was extremely upset about all the “Bieber Baby” headlines – again learning first-hand how the fame game can bring a lot of ugly baggage along with it.

LOOSE ENDS: Even though Kim Kardashian’s sudden flight to Minneapolis this past weekend included a meeting with her estranged husband, Kris Humphries, and the pastor who married them less than three months ago, don’t look for a reconciliation.

According to someone extremely close to the Kardashian clan, Kim’s intent was to “bring an amicable conclusion to this mess” and convince Humphries to keep mum about the couple’s 72-day marriage.

While the Kardashian-crafted pre-nuptial agreement technically nets her NBA player hubby nothing – if they were married less than five years – it’s said Kim will pay Kris a substantial chunk of change to prevent any future “tell-all” magazine stories or book deals he might be offered.

MEL MAKES MOVE: Hollywood gossips are whispering about the strong similarity – at least physically – between Mel Gibson’s new galpal, “Alphas” star Azita Ghanizada, and his long-estranged ex, Oksana Grigorieva, with whom he’s fought over money and custody rights regarding their daughter, Lucia.

As reported by TMZ and others, Gibson and Ghanizada have been spotted sharing a few romantic dinners in Tinseltown and exhibiting a lot of PDA.

Ghanizada, 31, is a native of Afghanistan and, during some of their serious moments, has been overheard briefing Gibson on her take on the war and political realities in her native land.

LOCAL LIGHTS: Congrats to Chicago comedians and writers Tim Robinson, Mark Raterman and Andy Miara – tapped by Comedy Central to develop “My Mans,” a show starring Robinson and Raterman as two best pals, with one always getting into tough scrapes but getting bailed out by the other.

Deadline.com reports the project will “offer a twist on sketch comedy as it weaves in and out of stand-along sketches.”

The road to Comedy Central started at the 2010 New York TV Festival, where Robinson, Raterman and Miara showcased a proposed pilot. That approach mirrors “It’s Always Sunny in Philadelphia,” which ended up on FX.

Robinson, Raterman and Miara are members of the Chicago improv troupe Cook County Social Club.
