Once again, Rihanna got rough, dirty and raunchy for her latest music video for her new single “Hard” from her latest album, Rated R.

This preview shows RiRi in the roles of both an army commander as well as a soldier…who just happens to take off her clothes to reveal little pieces of tape covering her nipples.

What else did you expect??

Kris Allen, winner of last season’s American Idol, has finally premiered a music video for his first single “Live Like We’re Dying.”

It’s pretty adorable, check it out below:

Britney Britney Britney…I commend you on your comeback with Circus, and the tour and all that…but my GOD girl you sure aren’t what you used to be!

Don’t get me wrong, I love me some Britney Spears, but you’d think at this point she’d have: a) A decent weave where you can’t see where her real hair ends and her extensions begin, and b) Music videos that are NOT boring as all hell.

“3″ is a great, incredibly catchy song, and while there are a few moments in the video that are kind of cute, it’s pretty much just Britney lip syncing and shuffling her feet to the beat.  Total waste of a music video.

But hey, at least her body’s back in shape?

What do you think?

Leighton Meester was on hand to join Weezer on-stage at their concert in NYC at the Hammerstein Ballroom to help them perform their new single “If You’re Wondering If I Want You To (I Want You To)”…and it was okayyyyy.

Not bad, just okay.

Check out Chris Brown’s second single “Crawl”!  Chris Brown will always be the guy who beat up Rihanna,  but you can’t deny his talent.  I actually really dig the song.

What do you think?
