Clint Eastwood's model daughter is reportedly following in Britney Spears' footsteps by ending her marriage to talent manager Jordan Feldstein, just days after the couple stunned family and friends by exchanging vows in Las Vegas. Francesca Eastwood wed actor Jonah Hill's brother on 17 November (13) and the couple filed its marriage certificate in Clark County last week (19Nov13), but now sources claim the week-long union is over. One insider tells media outlets the newlyweds had immediate regrets following their Simple Wedding Chapel nuptials, which were fronted by an Elvis Presley impersonator. The source tells Us Weekly Eastwood and Feldstein had "a wild night in Vegas" and "didn't know what they were doing" when they decided to get married. Eastwood has been dating Feldstein since splitting from longtime photographer boyfriend Tyler Shields earlier this year (13). Britney Spears annulled her 55-hour marriage to childhood friend Jason Alexander in early 2005. The couple wed in Las Vegas on New Year's Eve, 2004. Neither Feldstein nor Eastwood, who was spotted at a party in Los Angeles last week (21Nov13) without a wedding ring, have commented on the marriage story.
