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.

#137 (Billboard 200) Justin Bieber – My World 2.0

Happy 18th Birthday, Justin.

FUN FACT: Biebs made an appearance on Ellen, where Ellen, Usher, and his manager Scooter Braun gifted him with a rare Fisker Karma electric car valued at over $100 thousand. Only 5 people in the world own the car, including Al Gore, Colin Powell, and Leonardo DiCaprio.

#75 (Japan Hot 100): Lady Gaga – Born This Way

Cookies that say “bravery,” “acceptance,” and “love”? Even her food is pretentious.

FUN FACT: Gaga just launched her anti-bullying foundation, the Born This Way Foundation which will be run by Lady Gaga’s mother.

(Uncharted) Ne-Yo – Crazy Love feat. Fabolous

That’s funny, because Ne-Yo is one of my favourite washed up R&B singers who always wears a hat.

FUN FACT: Ne-Yo performed with Young Jeezy on Conan last week. Watch the performance below:

#72: Wiz Khalifa – When I’m Gone

Kissing on the mouth? I’m not too sure about that. Especially given that Wiz just proposed to Amber Rose.

(Uncharted): Birdman – Y.U. Mad feat. Nicki Minaj, Lil Wayne

As we announced earlier this week, Birdman signed Limp Bizkit to Cash Money Records.

It’s good to have you back in this ho, Fred. The ho was lacking without you.
