Adam Schlesinger, the multi-talented songwriter, producer and co-founder of the New Jersey rock band Fountains of Wayne — best known for its 2003 pop hit “Stacy’s Mom” — is hospitalized as he battles the coronavirus, according to multiple reports.

Schlesinger, 52, has been ill and on a ventilator in an upstate New York hospital for the last week, but is not in a medically induced coma as previously reported, his lawyer told Variety. The artist grew up in Montclair and graduated from Montclair High School.

Schlesinger co-founded Fountains of Wayne in 1995 and released five albums with the band.

He is a three-time Emmy winner, having worked in television — from “Sesame Street” to “Crazy Ex-Girlfriend” — and has written and produced for other bands, including his projects Ivy and Brooklyn-based Fever High.

He was nominated for an Academy Award and Golden Globe in 1997 for writing the title track from the Tom Hanks film “That Thing You Do!” He was also nominated for two Tonys in 2008 for “Cry-Baby” the musical.
