Timberlake's personal mixologist Eddy Buckingham created a cocktail using the star's own tequila Sauza 901, reported People magazine.
"The Three Five is a sophisticated yet approachable drink - perfect for a celebration. I serve it in a double rocks glass as that is how he usually enjoys his tequila," Buckingham said.
Buckingham stresses the twist in the drink comes due to the addition of orange bitters and cognac.
"The flamed orange zest garnish is a little bit of fun but also heightens the citrus nose on the cocktail," he added.
