Justin Bieber dissed by Nick Jonas for 'egging scandal' attack, Selena Gomez's exes engaged in Twitter feud over 'immature' felony prank? [VIDEO]

Just last week, Justin Bieber viciously egged his neighbor's house in Calabasas, resulting in approximately $20,000 worth of damages. Check out the crazy TMZ footage here:

UPDATE: Justin Bieber support from Kylie Jenner and Kelly Osbourne after 'egging scandal' police raid: reality starlets slam LA cops, crushing on Selena Gomez's ex?

Lil Za arrested during Justin Bieber home raid for felony drug possession: cocaine 'in plain view' after crazy 'egging attack,' both going to prison?

[WARNING, EXPLICIT LANGUAGE]

The two got into a verbal arguement and the cops were called (after Bieber managed to produce a major mess). The LA County Sheriff's Office has launched an investigation into the attack, and the "Believe" crooner could ultimately be charged with vandalism by the LA County DA. Because the damages are so extreme, the Biebs could even face felony charges.

And apparently former JoBro Nick Jonas thinks that's sort of lame.

@nickjonas: "Wait... egging is still a thing?"

Is the 21-year-old singer telling Selena Gomez's other ex that he needs to grow up and stop acting so immature?

Bieber has yet to mention any of this on Twitter. But do Mstars fans agree with the youngest Jonas Brother - what's with the random egg attack?
