Who doesn't want a piece of Justin Bieber?!

A Canadian company is taking the concept to a new level selling cloned sample copies of the pop star's DNA in necklace pendants, RadarOnline.com has exclusively learned.

Celebrity Gene obtained and extracted the DNA from a piece of Justin's hair and will begin selling the pendants at the end of May on their website -- with the cloned copies retailing for about $120 Canadian, and the original strand will sell for big bucks sometime in the future.

The DNA of the man accused of killing actress Jennifer Hudson's family was not found on the murder weapon, a Chicago court heard Thursday.

Illinois State Police forensic scientist Pauline Gordon said she tested the .45-caliber pistol and found a limited amount of DNA belonging to a male, but admitted that it excluded William Balfour, according to the Detroit Free Press.

Ryan O'Neal has taken a paternity test and RadarOnline.com has exclusively learned that he is not the father of the baby a woman claimed he was.

Jessica Zellars gave birth to a baby boy in February and a source close to her told RadarOnline.com that she believed that 70-year-old Ryan was the father of the child, but he has proven that indeed, he is not.

Ryan O’Neal recently got hit by claims that he fathered a child with a woman after a brief fling -- a charge he vehemently denies -- and he has agreed to take a paternity test to resolve the matter, which he believes will fully vindicate him, RadarOnline.com is exclusively reporting.

As we previously reported, Jessica Zellars has accused the 70-year-old Love Story star of fathering her two-month-old son, who she claims she conceived during their “brief romantic relationship.”

Having tracked down the mother who had him adopted as a baby, Matthew Roberts was even more shocked when she told him that his father may be notorious cult leader Charles Manson, and now he is hoping a court-ordered DNA test will prove his paternity once and for all.

“We’ve been trying to do an DNA test, even though it is a federal offence to take DNA out of a prison, so now we are trying to get a court order,” Roberts told RadarOnline.com in an exclusive interview.

Troubled Teen Mom Jenelle Evans is reportedly “devastated” after learning the truth about her young son’s paternity, and all the drama will be documented on the upcoming season of her reality show.

Andrew Lewis is listed on the birth certificate as the father of Jenelle’s baby, Jace, but she admitted that she cheated on him and was previously unsure who the father was, but now she’s learned that he is in fact the dad.

The question on everyone’s lips is -- will Khloe Kardashian take another DNA test, to prove that her father is Robert Kardashian?

A source close to the reality star tells RadarOnline.com that at present the 27-year-old has no plans to do so, but Khloe being Khloe, that could change!

The controversy continues to intensify over Khloe's true paternity with neither side backing down. While Kris Jenner was on GMA denying Star magazine’s exclusive report quoting Robert Kardashian’s ex-wife and widow, Jan Ashley and Ellen Kardashian respectively, the women are standing firm behind their claims.

Robert Kardashian’s widow broke her silence years after his death with the shocking revelations about his family exclusively to Star magazine, and now we can reveal more exclusive details about her, the Kardashian family and secrets that have been held for years.

Ellen Kardashian, was romantically involved with the famous lawyer for years, got engaged to him in 2002 and married a few months before Robert tragically passed away.  She revealed in a tearful interview that she loved Robert very much, and desperately tried to stay in touch with her stepchildren, Khloe, Kimberly, Kourtney and Robert.

The 63-year-old told Star that Robert expressed doubt about the paternity of Khloe.

Khloe is not a Kardashian!

Robert Kardashian's ex-wife and widow have come forward in a Star magazine exclusive in which they both claim that the late Kardashian expressed his doubts about the paternity of Khloe.

"Khloe is not his kid -- he told me that after we got married," Jan Ashley, 63, the woman who married Robert after Kris Jenner, revealed to Star.

"He just kind of looked at me and said [it] like it was a matter of fact. He said, 'Well, you know that Khloe's not really a Kardashian, don't you?' And I said…'OK,' and that was it."

Ellen Kardashian, 63, married Robert in 2003 just two months before his death, after dating for nearly six years -- and she has also come forward after eight years of silence to "tell the truth" about the Kardashian family.

Roku and Hex look like any other cute baby monkeys as they roll around together playfully, but the unique pair were actually created by scientists from the genes of up to six different animals.

Boasting the title of the world's first “chimeric monkeys” the primates were genetically engineered from the early-stage stem cells taken directly from monkey four-cell embryos to create 10 chimeric embryos that were then implanted into female monkeys, reported USAToday.com.

The scientific breakthrough was developed by experts at the Oregon National Primate Research Center, led by stem cell developmental biologist Masahito Tachibana.
