Spears puts custody battle in jeopardy

Troubled pop star Britney Spears has put her custody battle with ex-husband Kevin Federline in jeopardy by taking their kids out of Los Angeles, according to reports.

The 25-year-old flew to Las Vegas on Wednesday in a private plane with kids Sean Preston, 22 months, and Jayden James, 10 months, after news of her erratic behaviour on a photoshoot for America's OK! Magazine broke. Sources tell People.com the singer made special arrangements to have her hotel room childproofed prior to her visit.
