A musical reunion between Justin Timberlake and Britney Spears could be in the works after the singer said he's up for collaborating with his ex-girlfriend.

Spears said "Justin Timberlake is very good" last month while discussing who she would like to work with one day.

When informed of Spears' comments, Timberlake told E! News on Tuesday at the premiere of his Netflix concert documentary in Toronto that he "absolutely" would like to work with her, adding "I'm accessible, give us a call."

Spears and Timberlake were castmates on Disney's early 1990s version of the "Mickey Mouse Club." They dated for three years before breaking up in 2002.
