Beyonce has released two new tracks, "Bow Down" and "I Been On." The 31-year-old singer unveiled an audio clip of her first new material since 2011's 4 album on her website yesterday. The track was accompanied by a photo of the singer as a child standing in a room full of trophies.

Lyrics include the lines, "I know when you were little girls you dreamt of being in my world / Don't forget it / Respect that / Bow Down b****es." Elsewhere she sings, "I took my time to live my life but don't think I'm just his little wife / Don't get it twisted this is my sh*t."

The clip takes pieces from two different songs, "Bow Down," which has reportedly been produced by Hit-Boy and "I Been On" which is thought to have been made with Timbaland.

Beyonce's lyrics appear to refer to her absence from the music industry as she has become a mother to daughter Blue Ivy, now 14-months, and her husband, rapper Jay-Z, but her choice of words and apparent attitude have divided opinion. "I'm not sorry that @beyonce is a trend-setter and doesn't sound like everyone else. It's about changing the game #beyhive (sic)" one fan wrote on Twitter.

However, others were left surprised at her outburst. One user wrote, "how can u sing at the presidents inauguration then release this disgusting, offensive song @beyonce? I'm genuinely shocked (sic)"

Beyonce is set to start her Mrs. Carter World Tour next month.
