On Saturday, Oct. 26, the first-time parents-to-be were spotted enjoying a Kanye West concert at the Staples Center in Los Angeles, where the pair hung out (and boogied with!) Sudeikis' Saturday Night Live chum Kristen Wiig.
Wilde, 29, and Sudeikis, 38, first met in May 2011 during the season finale of SNL. Us exclusively broke the news in December of that year that the two were dating. "She's come to the [SNL] studio at Rockefeller Center, and they've gone out to dinner after rehearsals," an insider told Us during the budding romance.
And things went very, very well! Over a year later, in January 2013, a spokeswoman for the Change-Up actress confirmed that the two were engaged. "Thanks for all the sweet congratulatory love, friends!" Wilde tweeted at the time. "And may I compliment your savvy use of that nifty engagement ring emoticon."
Earlier this year, the brunette beauty gushed about one day starting a family with her future husband. "I am not trying to have kids now – there's no strict plan for anything in my life. What happens, happens," she said during an interview with Marie Claire for its April issue. "He's so good with kids...I've never before experienced looking at someone and thinking, 'That's who I want to raise a child with.'"
The two also have quite the love life -- behind closed doors, that is. In October 2012, Wilde admitted she's "blissfully, hopefully, wildly in love" during These Girls, an evening of monologues hosted by Glamour mag. Even more so, the two "have sex like Kenyan marathon runners."
This will be the first child for both Wilde and Sudeikis. The Horrible Bosses actor was previously married to Pitch Perfect screenwriter Kay Cannon from 2004 to 2010. Wilde was married to documentarian Tao Ruspoli for eight years before divorcing in 2011.
