Crystal Johnson wrote the song in collaboration with producers Stargate and Sandy Vee.

The singer "pours her heart out" in the chorus: "Want you to make me feel like I'm the only girl in the world/ Like I'm the only one that you'll ever love/ Like I'm the only one who knows your heart/ Only girl in the world." Fraser Mc Alpine of the BBC compared the song's message to that of the German fairy tale "Rapunzel"; Rihanna is not willing to throw her hair out of the castle for just any man to come and satisfy her, "particularly not someone who isn't prepared to make the climb up to her scarily high window."

Hello to you: A creative team have recreated a selection of controversial fashion ads, replacing hyper-sexualized female models such as in this American Apparel campaign, shot by Terry Richardson (left), with men (right) '[They] depict women in sexually vulnerable, pornographic positions where a lot of the model's facial expressions look like they've been drugged or they're drunk,' Ms Eagleson and Ms Wade argue.

Rihanna opened the American Music Awards with a medley of songs from Loud.

She began with an a cappella version of "Love the Way You Lie (Part II)", sitting on a stylized tree of lights above "a field of sable-colored blades of grass." She made the changes because the BPI wanted to avoid complaints like those received after the seventh-series finale of The X Factor on December 11, 2010, when Rihanna was criticized for wearing a provocative outfit and performing a suggestive, "disgusting" dance routine before the 9 pm UK watershed.

The video was praised by critics for its simplicity and colorful, pleasant imagery.
