Guy Fieri is 'all in' on officiating Kristen Stewart, Dylan Meyer's wedding

"We did hear that Guy Fieri from the Food Network officiates a lot of gay weddings," Stewart told Stern at one point. "So, the idea of that man—that sweet, sweet spiky-headed man—coming to our wedding and officiating, it just makes me laugh so much."

While visiting Today on Thursday morning, Stewart was surprised with a video from Fieri enthusiastically accepting:

"Is he joking?" Stewart responded, and when asked if her initial offer was serious, she said "absolutely."

Fieri also doubled down on Twitter:

The 31-year-old actress shared in the Today segment that Meyer proposed "months ago."

"I feel so lucky," she continued. "It's so nice to know something in this world. I'm so surely happy. I'm so stoked."

In Spencer , Stewart portrays the late Princess Diana. The film is described as "an imagining of what might have happened during those few fateful days" over the Christmas holiday at the Queen's Sandringham Estate before Diana's divorce from Prince Charles. Watch the trailer below.
