The New Kids on the Block member will guest-star as himself on the Jan. 14 episode of the CBS comedy.
“I had a lot of fun on Angel From Hell,” McIntyre, 42, tells PEOPLE exclusively of working on the Jane Lynch sitcom, which was initially scheduled to premiere in November but will now debut in the new year.
McIntyre previously worked with Angel actress Maggie Lawson on Psych and says it was “great” to be reunited once again.

“She’s super funny and a total pro,” says McIntyre, who recently filmed a pilot for Pop TV. “And I’m not just saying that because she got tickets to a New Kids concert for Christmas when she was 7 and screamed like maniac.”
Angel from Hell premieres Jan. 7 at 9:30 p.m. ET on CBS.
