MEMPHIS, Tenn.  — Award-winning singer and actor Justin Timberlake has agreed to be part of the ownership group assembled by billionaire Robert Pera in his attempt to buy the Memphis Grizzlies, said a person familiar with the situation.

The person said Friday that Pera “has assembled a strong ownership group that includes Justin Timberlake, other community leaders from Memphis, and highly strategic national partners.” Pera agreed in June to buy the Grizzlies from Michael Heisley for $350 million.
