Saturday Night Live alum Jason Sudeikis opened up to the August issue of Elle about his love life with actress Olivia Wilde and also how she helped him lose weight.

Sudeikis said that little things - such as "not eating barbeque sauce with my pizza at two in the morning" - contributed to his weight loss, but the main factor was his "workout" in bed with Wilde.

"The truth is, I'm not getting up an hour earlier and walking on a treadmill. I have the greatest workout partner in the world," he said. "And you don't need a gym membership for that kind of workout."

Wilde, 29, previously admitted that their sex was "like Kenyan marathon runners" and that she is "blissfully, hopefully, wildly in love." Sudeikis, who divorced actress Kay Cannon in 2010, told the magazine that Wilde is the girl in his dreams.

"I mean, what better story than meeting the girl of your dreams, sweeping her off her feet, and then being strong enough to carry her out? That's my story," the 37-year-old said. "It's the desire to look across the aisle, or to look next to you while walking through the crazy, weird red-carpet situations. And see someone right there for me now-and hopefully forever."

When asked what Broadway musical taught him about love, he replied songs from La Cage aux Folle, which he admittedly will sing "in the most private of karaoke rooms." 

The couple started dating in November 2011 and have plans to get married next spring.

"We have jobs lined up. Our friends work in the business. We have to find a perfect venue. It starts there," the We're the Millers star added. "The where is first, then the when and the who. The why and what we have on lockdown." 

The couple was last seen on the red carpet attending the 2013 ESPY Awards held in L.A. on Wednesday.
