Actress Julianne Phillips, looking to give "The Boss" the boot from their 3-year-old marriage, has claimed "irreconcilable differences" with rock superstar Bruce Springsteen. Phillips' one-page divorce petition filed Tuesday in Los Angeles Superior Court seeks unspecified spousal support and says property rights will be determined later, said her attorney, Arlene Colman-Schwimmer. Springsteen, known as "The Boss," has recorded such rock hits as "Born To Run," "Thunder Road" and "Tunnel of Love," which was dedicated to Phillips.Also, rocker Bob Seger has filed for divorce after less than 10 months of marriage to actress-model Annette Sinclair, but his manager says the two will remain good friends. Seger, 42, and Sinclair, 27, had signed an agreement concerning alimony and a property settlement, according to Seger's suit, which was filed in Oakland County, Mich., Circuit Court. Seger's manager, Edward "Punch" Andrews, said the singer's divorce action, filed Monday, is uncontested.
