Jennifer Esposito and Bradley Cooper have split after four months of marriage. Esposito filed for divorce on Tuesday in Los Angeles County Superior Court, citing irreconcilable differences. Esposito, 35, and Cooper, 32, wed in late December after announcing their engagement in October. A rep for Esposito tells TMZ.com: "Jennifer asks that you respect her privacy at this time." Cooper's rep calls the split mutual and tells the site, "actually they've been separated for quite a while." Esposito appeared in last year's Best Picture Oscar winner Crash and starred in the 2005-06 WB series Related. Cooper starred in the short-lived 2005 FOX sitcom Kitchen Confidential and appeared in last summer's Wedding Crashers.
