At the end of each week, #Top40Tweets lists a cross-section of artists on the current pop charts and puts their tweets on display (along with their current chart number) for your enjoyment/scrutiny. This week, we look at 5 artists on the Billboard Music Charts.

#28: LMFAO – Sexy And I Know It

I’m skeezy and I know it.

FUN FACT: LMFAO recently filed a claim to the US trademark office, attempting to copyright the acronym LMFAO. In doing so, they had to spell out what the acronym stands for:

Laughing my FREAKING ass off? I guess LMFAO are a little more PG than we thought. Except for the whole Rub-N-Tug thing.

#33: Chris Brown – Turn Up The Music

Immediately after taking that photo, Chris Brown hit the male fan in the head with a wooden bat, and asked the man if he was “some kind of gay.” Classic Breezy.

FUN FACT: According to Media Take Out, Chris Brown recently sent a message to Ashton Kutcher via mutual friend Diddy. The message? Stay away from Rihanna.

#44: Bruno Mars – It Will Rain

ALL THREE. But not in that order. HUG > BOY BAND > KNIFE FIGHT.

FUN FACT: Here’s a video of a 4-year-old Bruno Mars, impersonating Elvis. Oh yeah, Pauly Shore is there too.

#(Uncharted) Afrojack & Shermanology – Can’t Stop Me

I call bullshit. There’s just no way DJ Afrojack knows how a blind dog feels after running into a fire hydrant. No way.

FUN FACT: Afrojack has been collaborating with Shakira in the studio lately, so expect to hear the results of that partnership this summer.

(Uncharted) Mike Posner – Top Of The World

KNOWLEDGE!
