Britney Spears starts 30-day rehab after sons issue firm ultimatum

Britney Spears voluntarily entered a 30-day rehab program after an intervention by her sons, Sean Preston and Jayden James Federline, who reportedly gave her an ultimatum to seek help following her March DUI arrest and ongoing sobriety concerns; insiders say she reluctantly agreed to go to preserve her relationship with them, continuing a pattern of family-influenced steps after past sobriety coaching changes and her conservatorship history.
