Since Nobel judges announced Thursday that rock legend Bob Dylan would receive this year's prize for literature, they have yet to hear from the "Like a Rolling Stone" singer.
Last week he became the first musician to be awarded the Nobel Prize in literature, a prestigious award whose previous recipients include William Faulkner, Gunter Grass and Samuel Beckett.
Dylan, 75, is the first American to receive the literature prize since Toni Morrison in 1993.
The famously private star has performed since the news broke but has so far said nothing in public about the honor.
"I have called and sent emails to his closest collaborator and received very friendly replies. For now, that is certainly enough," the Nobel academy's secretary, Sara Danius, said Monday, according to The Guardian.
Nobel recipients are honored at an annual ceremony, which this year will be held Dec. 10 in Stockholm. Danius added she's not worried and believes Dylan will show up to accept the prize along with other awardees.
His silence isn't too surprising, since he's not one to give interviews.
His official Twitter account shared news of the prize after it was announced Oct. 13.
A retweet that day of President Barack Obama, who wrote, "Congratulations to one of my favorite poets, Bob Dylan, on a well-deserved Nobel" was the last post on the account.
An ABC News request for comment on the award from Dylan's representative was not immediately returned.
