Spears cited Timberlake last month when asked about her dream collaborators, and Timberlake recently responded in kind to E! Online at the Toronto International Film Festival.
"She did? Sure! Absolutely, absolutely," Timberlake said, upon learning that Spears name-dropped him as a potential collaborator. "I have a 17-month-old, so I don't get the headline news. I apologize for not being in the know.
"I'm accessible," he added. "Give us a call!"
Timberlake has never appeared on the same song as Spears.
Previously, the former NSYNC star admitted that he wrote his 2002 hit single "Cry Me a River" after a heated argument with Spears, whom he was dating at the time.
