Fans in Los Angeles cheered "We want Boston!" at points during both Games 1 and 2 of the Western Conference Finals this week.
The Lakers, like the Celtics over the Magic, opened up a 2-0 series lead against the Suns.
The past two NBA champions are now just two wins away from their second meeting in three seasons.
"I have zero reaction to that," Kobe Bryant said when asked about the chant.
Lakers coach Phil Jackson says he didn't know what was going on at the time, but was upset after learning of the chants.
"I didn't understand it [at the time], I'm sorry, I'm not that good [at paying attention to cheers during the game] to understand it," Jackson said. "But after the game I was disappointed when I heard it was [going on]."
The Celtics and Lakers have played each other in the Finals 11 times.
