What’s a pregnancy announcement without a little bit of drama? Following the British monarchy’s confirmation that Prince William and Duchess Kate Middleton are expecting their second child, a new Prince Harry tell-all is revealing shocking details regarding the life of the brothers' late mother, Princess Diana. In the biography “Prince Harry: Brother, Soldier, Son," royal-family biographer Penny Junor claims not only was Princess Diana of Wales an unfit mother, she also allegedly delivered a death threat at one point to Prince Charles’ current wife, Camilla Parker-Bowles, Radar Online is reporting.

Junor states Diana was so “consumed with jealousy” over Bowles two-decade romance with Prince Charles, she allegedly threatened her life. “I’ve sent someone to kill you,” Junor alleges Diana told Bowles in a phone call. “They’re outside in the garden. … Look out of the window; can you see them?” Junor does not specify when the alleged phone call occurred.

Princess Diana’s rumored rage toward Bowles and her eventual divorce from Prince Charles in 1996 was hard on the couple’s two children, Prince William, now 32, and Prince Harry, now 29, Junor says. “While their nannies could keep them occupied and the protection officers could keep them safe, no one could protect them from the emotional extremes of their mother,” she says. “Diana confided in her boys and sought comfort from them, even though they were so young.”

Junor says Diana would seek solace from Prince Harry during his younger years in the late 1980s, early 1990s. “[She] expected [him] to comfort her as she ricocheted from one terrifying emotional outburst to the next,” she says. While Junor does not deny Diana loved her sons, she does say the royal was “obsessive” in her attempts to make sure they favored her above all, even firing nannies who she felt connected emotionally to the boys. “One of her favorite phrases was: ‘Who loves you most?'” Junor says. “She loved her boys more than anyone else on earth but she wanted them to love her better than anyone else, too."

Princess Diana and Prince Charles divorced in August 1996 after nearly a decade of speculation regarding their turbulent marriage. Diana died in a car accident in Paris nearly a year later with her boyfriend, Dodi Al Fayed. In April 2005, Prince Charles finally married Bowles and she became Britain's Duchess of Cornwall.
