By ANDREW DALTON and RYAN PEARSON (AP Entertainment Writers) LOS ANGELES (AP) — Britney Spears and her husband Sam Asghari separated nearly three weeks ago, and he is seeking spousal support and attorneys’ fees in their divorce, according to his divorce filing. Asghari, 29, filed his petition to dissolve his 14-month-old marriage to the 41-year-old pop superstar in Los Angeles County court late Wednesday. Like the vast majority of those who file for divorce in California, he cites irreconcilable differences as the reason for the split. The document lists the couple’s separation date as July 28, though reports of the split did not emerge until Wednesday.
