Jason Sudeikis Weight Loss: Actor Credits Olivia Wilde For Helping Him Drop 20 Pounds

Jason Sudeikis has found his stride.

The "Saturday Night Live " star, who just wrapped his final season as a full-time cast member, is set to appear in "We're the Millers" with Jennifer Aniston this summer and is set to walk down the aisle with fiancee Olivia Wilde in the near future (or at least we hope so).

In the new issue of Manhattan magazine, Sudeikis opens up about his exciting career change and the secret behind how he shed 20 pounds in one year. Hint: his better half had something to do with it.

You never really leave that place, and it never leaves you," the 37-year-old actor says of "SNL ." "Its an emotional journey getting through a season, much less the final one.

Still, that emotional journey led Sudeikis to pack on the pounds, due to late night snacking and socializing. That's when he made a conscious effort to try and lose some weight, but in actuality, that number on the scale got lower thanks to Sudeikis' romance with Wilde .

Being happy, and in love, for me, was the secret," he admits of his weight loss. "I feel like I returned home to myself as an individual through the process of falling in love with the sweetest woman Ive ever known.

And that woman will soon be his wife -- and possibly the mother of his children. When asked whether or not he wants kids of his own, Sudeikis gushes to Manhattan , Ive certainly found a partner Id be just as willing to make a child with as make a movie with, so for me thats a win-win.

As for when that Wilde wedding will happen , Sudeikis says he doesn't know, but the couple have sort of devised a plan.

We want it to be not a plane-train-automobile situation," he admits, "and not on Thanksgiving or Memorial Day weekend.
