Grant Williams is campaigning hard for Boston Celtics teammates Kemba Walker, Jayson Tatum, and Jaylen Brown to make this year's All-Star Game. If all three of them make the 12-man cut, the Celtics rookie has promised to dye his hair pink for a month.

Watch him give his hilarious campaign speech below, per John Karalis of MassLive:

Walker, Tatum, and Brown are playing at a high level this season and are a huge reason why the Celtics currently have the No. 2 seed in the Eastern Conference.

Kemba Walker is almost a lock and should have no problem making his fourth appearance in the All-Star Game. The 29-year old has done a magnificent job filling in the void of Kyrie Irving's departure and has emerged as Boston's leading scorer, averaging 21.7 points per game.

Likewise, Jayson Tatum has a pretty high chance to make his first All-Star selection given the way he has emerged as a legitimate star this season. The third-year forward is not far behind Walker when it comes to scoring, netting 21.3 points a night to go along with 6.9 rebounds and 2.4 made triples per game.

That leaves Jaylen Brown, who is also in the midst of a breakout campaign for the Celtics. The two-way swingman is putting up career numbers across the board, averaging 19.9 points and 6.7 rebounds while shooting nearly 49 percent from the field. Realistically speaking, Brown probably has the slimmest chance of making the All-Star team among the three despite his massive jump his season.

Walker is currently third among East guards (behind Irving) in the second returns of All-Star fan voting, while Brown is seventh. Tatum, meanwhile, is fifth among East frontcourt players.

Walker still has a shot to get the starting nod of the All-Star Game as he did last season, while Tatum and Brown would likely get in as reserves, should they make the cut.

Grant Williams should brace himself and have that pink hair dye ready just in case all three of his teammates are picked.
