The entertainer made her first 40-city national concert tour, Live in Concert, in support of Here We Go Again. The tour, from June 21 to August 21, 2009, had David Archuleta, KSM and Jordan Pruitt as opening acts and Lovato and Archuleta received the Choice Music Tour award at the 2009 Teen Choice Awards.[63] In March 2010, Lovato and Joe Jonas recorded "Make a Wave" as the second charity single for Disney's Friends for Change.[64] In May Lovato guest-starred as a teenage schizophrenic in the sixth-season Grey's Anatomy episode, "Shiny Happy People". Although critics praised her versatility, they were underwhelmed by her acting and felt that her appearance was designed primarily to attract viewers. Later that year she headlined her first international tour, the South American Tour, and joined the Jonas Brothers Live in Concert tour as a guest.
