Beyonce is back! The R&B songbird previews two new songs, 'Bow Down' and 'I Been On' via her Tumblr page on Sunday (March 17).

On 'Bow Down,' produced by Hit-Boy, Queen Bey talks her s--- and lets everyone know who is the ruler of the R&B game. "I know when you were little girls / You dreamt of being in my world / Don't forget, don't forget / Respect that, bow down bitches," she sings. She then adds, "I took some time to live my life / But don't think I'm just his little wife / Don't get it twisted, get it twisted / This is my s--- / Bow down bitches."

Then at the 1:30-mark, Bey flips the script and gets trill over the operatic chopped-and-screwed banger, 'I Been On.' On the track, produced by Timbaland and Polow Da Don, she continues her kingly braggadocio talk. "I'm bigger than life / My name in the lights / I'm the No. 1 chick, I don't need no hype / The capital B means I'm 'bout that life / The capital B mean I'm 'bout that life," she boasts.

Bey also gives props to her H-Town heroes Willie D, the late Pimp C and UGK.

We don't know if this is a warning shot to the other female R&B singers or if Beyonce was simply joking around. Either way, it looks like Mrs. Carter is bringing some heat this spring.

There is still no official statement regarding her upcoming fifth album, but judging by this single, it's most likely coming soon.

So prepare yourself for the Beyonce onslaught in 2013. Bow. Down. Bitches!
