Ashlee Simpson, 26, filed for divorce from Pete Wentz, 32, on Tuesday.
The couple has been dating since 2006 and got married on May 17, 2008. They have a 2-year-old son together, little Bronx Mowgli.
The reason for the split claimed by Simpson is "irreconcilable differences". She asked for joint legal custody — and primary physical custody — of their son and she is also asking the court to restore her name to Ashlee Nicole Simpson (she had it changed to Ashlee Simpson-Wentz less than month after their wed).
