Kevin Federline married longtime girlfriend Victoria Prince earlier this month, which reportedly infuriated Britney Spears, his ex-wife. The couple had their ceremony at the penthouse of the Hard Rock Hotel & Casino in Las Vegas, with Federline, 35, wearing a traditional black suit and Prince, 30, wearing a flowing white wedding gown.

Their daughter, Jordan Kay, was the flower girl. When Spears heard the news, she was allegedly devastated and “screamed uncontrollably,” an insider told the National Enquirer. “Then she collapsed in tears. The wedding caught her by surprise. She wasn’t invited and she didn’t even get a call from Kevin to let her know he was marrying Victoria.”

Spears and Federline married in 2004, after dating for three months. They have two sons together, Sean Preston Federline and Jayden James Federline. Their relationship was documented on the UPN series, "Britney and Kevin: Chaotic," back in 2005, which showed their courtship, engagement and wedding through personal home videos. They later divorced in 2007, with Spears citing irreconcilable differences.

Still, the 31-year-old pop star was reportedly overcome with emotion after hearing about Federline’s most recent marriage. “It was hard for Britney because she’s long suffered from the delusion that she and Kevin would one day get back together and raise their two boys,” a source said. “Even after Jordan was born, Britney held onto her fantasy of reconciliation with Kevin. But the wedding has crushed her, and she’s angry that she definitely won’t be getting Kevin back.”

The “Toxic” singer is currently dating David Lucado, a former bartender and insurance agent who now works at a legal firm.
