Despite the day-early leak of Britney Spears' comeback single, 'Hold It Against Me', the official release today has been met with a great reception. 

Tweeting to her fans just a few hours ago (January 11), Spears wrote:

"Seriously, I have the best fans ever. I love you all so much!! Everything I do is for you! xoxo Brit"

The single is already receiving rave reviews for its deviation from pop and nod to dubstep, with Rollingstone.com giving it 4 out of 5 stars:

"'Hold it Against Me' is prime Britney, packed with aggressive electro jitters, a Euro-cheese riff that's strangely close to AC/DC's "Dirty Deeds Done Dirt Cheap," and a weird breakdown where Brit moans, blows kisses, and snaps her gum."
