"Look at Me Now" is a song by American singer (and occasional rapper) Chris Brown, featuring American rappers Lil Wayne and Busta Rhymes, released as the second single from Brown's fourth studio album F.A.M.E. on February 1, 2011. The artists co-wrote the song with its producers Afrojack, Diplo, and Free School, with additional writing from Ryan Buendia. Musically, "Look at Me Now" is a "Dirty south-inspired" hip hop song that features "thumping bass, spacy synth and horn jam sounds."

Critical reception towards the song was positive, where critics noted it as a standout track on the album, and praised Busta Rhymes and Lil Wayne's rap verses. "Look at Me Now" proved to be successful in the United States, where it reached number six on the Billboard Hot 100 chart, making it Brown's highest chart position since "Forever" (2008). It also reached number one on the Hot Rap Songs and Hot R&B/Hip-Hop Songs charts. Internationally, the song charted in Australia, Canada, France, New Zealand and the United Kingdom.

An accompanying music video was directed by Colin Tilley and filmed in Los Angeles, California. It features numerous scenes of Brown, Busta Rhymes, and Lil Wayne in a smoke-filled, graffiti-covered parking garage, where a Step Up-type dance-off is held. The video received a positive response from critics for displaying various colors and intricate routines performed by Brown and several dancers. The song won three awards at the 2011 BET Awards for Best Collaboration, Viewer's Choice and Video of the Year. Several artists have covered the song and released their own remixes, including Karmin, Justin Bieber, Trey Songz and Da Brat.
