Olivia Wilde will marry “SNL” star Jason Sudeikis next spring in upstate New York, and she’s chosen Monique Lhuillier to design her bridesmaids’ dresses. The “Tron” actress dished a few details about her wedding to guests at a Monday bash at The General to celebrate her April Marie Claire cover. She added that the long engagement bucks her family’s usual trend of getting hitched months after a proposal. Also at the dinner were Kristen Wiig, Norah O’Donnell and Ari Graynor.
