Britney Spears recently shared a TikTok video of herself dancing to Justin Timberlake's song and acknowledged their breakup that happened 20 years ago. The Ooh La La singer and Justin Timberlake dated for three years until their breakup became the talk of the town in 2002. However, there doesn't seem to be any bad blood between the two exes as Britney posted a video dancing to one of Justin's songs Filthy and gleefully called him a genius.
