Cat Deeley Says Stephen 'tWitch' Boss Will 'Forever Be Part of Our Family' at So You Think You Can Dance (Exclusive)

Cat Deeley is looking back at her memories of Stephen "tWitch" Boss one year after his death.

The So You Think You Can Dance host, 47, tells PEOPLE that “it's so important that we remember tWitch and exactly who he was and how he was, and how he had a smile for absolutely everybody.” 

Deeley shares that tWitch, who was a finalist in season 4 of the Fox dance competition, will “forever be part of our family” following his death by suicide at age 40 on Dec. 13, 2022.

“It's a thing that we have with everybody who comes on the show, and no one has forgotten, ever,” she adds.

The television personality also recalls sharing a laugh with tWitch on the set of SYTYCD, where he went on to be an All-Star for three seasons and a judge in 2022.

“He would always come up to me and give me a great big massive hug. And he'd sweat, oh my Lord, like nobody... Buckets. Buckets and buckets,” she shares. “And I'd hug him and I'd literally just be drenched. And I was like, ‘What am I going to do now?’ And he'd laugh and laugh and laugh, and we'd laugh about it together.”

In another memorable moment from the set, Deeley remembers attempting to try some of Stephen’s moves.

“I'm an English girl with an English accent, and when I try and get all down with the kids and street [dance], it doesn't quite work,” she explains. “So, I took his grill and I put it in my, I said, ‘Hand over your grill. I can be as street as anybody else.’”

She continues: “He was just kind and talented, and I miss him very much.”

Deeley notes that Boss’ wife Allison Holker Boss, who will join So You Think You Can Dance as a judge for season 18, is “very raw and very emotionally available” when discussing her late husband.

“I think the more we can keep those conversations happening, the less people feel they are alone,” she adds.
