Although Britney's "Oops!..I Did It Again" and *Nsync's "No Strings Attached" are still churning out mega-hits, the two pop acts are already planning their next albums.

Britney is currently in Stockholm to start working on her third album with Max Martin, Billboard reports.

Meanwhile, the rumour is that *Nsync could release their next album as early as June.

*Nsync heartthrob Justin Timberlake told Billboard that the group hopes to "experiment a little".
