Hours after Radar Online claimed the Longest Week actress, 28, was planning to marry the Saturday Night Live standout, 37, in Sudeikis' home state of Kansas, Wilde debunked the rumor via Twitter.
"No, I'm not engaged, but I am at the Stones show and holy sh-t Ronnie Wood you got style, boy. It's just a fact," the O.C. star tweeted. "Trying to score a shoe pic." (Fellow lovebirds Katy Perry and John Mayer also attended the Rolling Stones concert.)
In October, a source close to Wilde and Sudeikis assured Us Weekly the two are in no rush to wed. "They've both been married, so they've already experienced that and know what it entails," the source explained. "It's something for down the road."
(Sudeikis was married to actress and 30 Rock writer Kay Cannon from 2004 to 2010. Wilde finalized her divorce from filmmaker Tao Ruspoli in September 2011 after eight years of marriage.)
After splitting with Ruspoli, a 37-year-old Italian prince, Wilde wasn't sure if she would ever find love again.
"Dating was a lot more painful than I'd ever imagined," she revealed on Lifetime's The Conversation With Amanda de Cadenet in May. "Learning to be by myself and be OK with it, and not need the validation of another human being, that has been the biggest challenge. But I know coming out of that, I'll be a better person -- and a better partner -- eventually, for someone."
