Watch: Justin Timberlake challenges Giannis Antetokounmpo, sinks incredible shot

MILWAUKEE -- Superstar Justin Timberlake was in Milwaukee practicing his trick shots on the Bucks' training court and making bets with the team.

Friday, Sept. 21 Timberlake posted to Instagram a video on the court inside the Milwaukee Bucks' training facility, the Froedtert & Medical College of Wisconsin Sports Science Center.

In the video, he attempts a near-half-court shot under one condition: he sinks it and Giannis Antetokounmpo has to get to his concert Friday night.

Timberlake captioning the video, "@giannis_an34 if I make this from the deer the you gotta come to the show..."

On Saturday, JT shared a photo on his Instagram Story with him alongside the Greek Freak. Looks like he made it to the show!
