Clint Eastwood's daughter and Jonah Hill's brother are having their week-long marriage annulled.

Francesca Eastwood married Jonah's brother Jordan Feldstein in a secret Las Vegas ceremony on November 17. But sources close to the couple say it was a drunken mistake when they got hitched at the Simple Wedding Chapel - in front of an Elvis Presley impersonator.

"Francesca had immediate regrets. We shot her the day after the nuptials and she wasn't wearing a wedding ring. We shot Clint Eastwood a few weeks ago asking for marriage advice and he told our photographer to not rush into anything," TMZ reports.

The wedding came after Jordan, who is Maroon 5's music manager, was targeted by an alleged ex-girlfriend who posted messages and photographs from their relationship on controversial website The Dirty. He allegedly made efforts to have the posts removed from the site, days before he married Francesca.

Clint's daughter Francesca, whose mother is actress Frances Fisher, was most recently seen in stepmother Dina Eastwood's reality series Mrs. Eastwood & Company - which chronicled her relationship with then-boyfriend, photographer Tyler Shield. Clint, 83, and Dina revealed they had split earlier this year and the 48-year-old TV star filed for divorce in October. The screen legend is now dating Erica Tomlinson-Fisher.
