Justin Bieber, 'Eclipse' cast make for July 4 fireworks on NBC

Justin Bieber will set off sparks of his own when he performs at the "Macy's 4th of July Fireworks Spectacular" on NBC on Sunday (July 4).

Here's a sneak preview of Bieber singing his hit song "Baby" to a crowd of excited fans under the Queensboro Bridge. It kinda sounds like you can actually already hear fireworks going off in the background.

Guess who else is coming? You guessed it! NBC says Robert Pattinson, Kristen Stewart, Taylor Lautner and other stars from the "Twilight: Eclipse" cast are also participating in the event, which airs at 9 p.m. ET Sunday.
