#10. Britney and Lynne Spears

One constant in Britney's chaotic life has been the presence of her Louisianan mama, Lynne. But, along with her hair and her dignity, Britney gave her mom the Ugg boot this year. Reportedly ticked about being pressured into rehab in February, the singer distanced herself from her family and delivered an upsetting letter to Lynne in front of hordes of paparazzi in June. After Britney lost custody of her two sons in October, her mom flew in to try and patch things up. But by December it seemed little had changed: Britney spent her birthday with the same date as last year, Paris Hilton.
