Michael Phelps can soon add another accomplishment to his already-glowing résumé: Author.
The record-shattering Olympic swimmer has earned an advance estimated at $1.6 million from Simon & Shuster for a book, to be titled "Built to Succeed," the New York Post reported Thursday.
The deal was brokered by the Waxman Literary Agency, working with Phelps' longtime talent manager Peter Carlisle of Octagon, the newspaper reported, adding that the entry price for negotiations was $1 million.
At least a half-dozen major publishers considered the book, billed as an "inspirational memoir," before Dominick Anfuso, the editorial director of Simon & Shuster's Free Press imprint, landed the deal, according to the report.
It's been a busy week for Phelps, who also plans to host the season premiere of "Saturday Night Live" and appear as a presenter at MTV's 2008 Video Music Awards.
On Thursday, Phelps was in New York City, filming a cameo for the HBO series "Entourage."
Phelps has already earned a $1 million bonus from Speedo for breaking Mark Spitz's record for the most gold medals earned in a single Olympics.
