Paul Pierce brought a friend to Kevin Garnett's NBA Finals watch livestream.  A friend he paid for the day.

Pierce, who was fired by ESPN for partying with escorts on IG Live, surprised his former teammate by stunting the sex worker.

"This my girlfriend for the day, they got a website girlfriends for the day," Pierce said of the woman next to him.

Garnett tried to change the subject.

Pierce, who appeared to be very drunk during the filming, is promoting his own "After Dark" live stream.

So it's all on brand for the bball star turned trainwreck.
