Britney - who has two sons, 15-month-old Sean Preston and three-month-old
Jayden James, with Kevin - was seen enjoying a string of late nights with
Paris immediately after dumping Kevin.
She was also photographed on four occasions not wearing any underwear.
The 25-year-old singer has since apologized to her fans, via her official
website, for her behavior, saying: "Thank God for the new underwear line
from Victoria's Secret!
"I look forward to a new year, new music and a new me. I'm just getting
started!"
Britney has not released any music for two years but has been in the
recording studios since she filed for divorce.
