The album's second and final single, "Remember December" failed to match the success of its predecessor, but it peaked at number 80 on the UK Singles Chart.
The entertainer made her first 40-city national concert tour, Live in Concert, in support of Here We Go Again.
The following year, Lovato was cast as the titular character in the television series Sonny with a Chance (2009–2011), and released her sophomore album, Here We Go Again, which became her first to top the Billboard 200 chart.
After the release of additional television films and their soundtracks in 2010, including Camp Rock 2: The Final Jam, Lovato's personal issues put her career on a hiatus and led to the discontinuation of Sonny with a Chance after a second season.
Her fourth album, Demi (2013), generated the single "Heart Attack", which became her third top 10 in the US.
