Press had earlier shared Musser was suffering from "a severe case of Covid," and that she believed he died from the illness. He was both vaccinated and boosted, FOX News reported. 

"Alec was a wonderful man. He was the best fiancé. The best dog dad. Very kind hearted person," Press said of Musser, whom she got engaged to a little over a year ago. "Seeing how many messages and people have reached out to me from his childhood…In the last couple of days, people I’ve never even met, sending me photos from him from high school and when he was in there wedding…He was so loved and touched by so many people."

He played a role described as "Water Park Stud" in 2010's "Grown Ups."

Sandler, who co-wrote, co-produced and starred in the film, posted a tribute to Musser on Instagram, writing: "I loved this guy. Cannot believe he is gone. Such a wonderful, funny good man. Thinking of Alec Musser and his family and sending all my love. A true great sweetheart of a person."

Salma Hayek Pinault, who played Sandler's character's wife in "Grown Ups," also paid tribute to Messer on social media.

"He was so kind professional and absolutely hillarious," Hayek Pinault wrote. "His early departure breaks my heart. I feel so blessed that I got to meet him. My sincere condolences to his family and loved ones for this great loss."

Musser was born in New York and later attended the University of San Diego. He won the role of Del Henry on the long-running ABC soap opera in July 2005 after winning the second season of the reality show "I Wanna Be a Soap Star." He also appeared on "Rita Rocks" and the TV movie "Road to the Altar" in 2009, and on ABC's "Desperate Housewives" in 2011.
