The first family enjoyed the performance during the White House's celebration of soul music from Memphis, Tennessee, the Mirror reported.
In the video Michelle and Obama are seen grooving, with the US president not being able to resist singing along.
Obama exchanged words with the singer and his wife Jessica Biel, who accompanied him at the event.
Announcing the engagement of two White House staff members, the President encouraged the couple to seek wedding tips from Timberlake and Biel, who tied the knot last year, and quipped: "Justin, they are looking for a wedding singer, just sayin'."
