Braxton revealed to Essence that she originally intended the song "Hot Sugar" to be released as the lead single from her second album, saying "given everything that happened to Vince and I this year, and everything we went through in our marriage, this song was fitting to me and Vince", explaining "I've been in love before, and I've gotten my feelings hurt before but I've never experienced passion until I met Vince". She added "I've never argued this much with a person, and I've never loved this hard. That's what this song is about." Singer-songwriter Lady Gaga, who was signed by Braxton's best friend and Streamline Records founder Leshelle Driver in 2007, promoted the single via social networking siteTwitter, to over 31 million followers. VH1 writer Bené Viera commented that "Gaga is like family to Vince & Tamar" and that it was "sweet of her to use her super fame to show Tamar love".
