Newly pregnant actress Olivia Wilde and her fiance Jason Sudeikis have reportedly changed their wedding plans in light of her pregnancy.

Wilde, 29, and Sudeikis, 38, who originally planned to wed next spring, decided to "do something small before the baby comes," earlier than they planned, an insider told InTouch.

"They're both low-key, so neither stressed about changing plans," the source added.

Wilde's rep announced that the actress is expecting her first child to Us Weekly on Oct. 27.

The couple began dating in May 2011 after they met during the season finale of Saturday Night Live, which he was a cast member of at the time. The Hollywood couple became engaged in January of this year. After Wilde's rep confirmed the news that he asked her hand in marriage, Wilde replied to an influx of wishes she received from her followers on Twitter.

"Thanks for all the sweet congratulatory love, friends!" Wilde wrote, following many notes of congratulations. "And may I compliment your savvy use of that nifty engagement ring emoticon." 

A source said at the time that Sudeikis popped the question because he felt he had found "the one."

"He finally found the one that made him want to commit," the source told Us Weekly. "They've both been through it before and this has just felt right from the get go. Everyone is happy for them."
