Emma's half sister, Grace Nickels — the daughter of her mother and former L.A. Guns bassist Kelly Nickels — was born in early 2001. In a 2005 interview, Roberts stated that she is "definitely closer to [her] mum and stepdad and [she doesn't] see [her] real father much". In a Wild Child interview with Alex Pettyfer, she refers to Nickels as her "Dad". After rumours that she was dating co-star Alex Pettyfer, Pettyfer confirmed that he and Roberts "enjoyed a fling" on the set of Wild Child, with Pettyfer even getting Robert's initials on his wrist. The two remain close friends.
In 2001, Roberts also had a role in Leif Tilden's 10-minute short bigLove (which also starred her future stepfather, Kelly Nickels), and was an uncredited extra in one of Julia Roberts' scenes in America's Sweethearts. She went on to appear in smaller roles in two family films: in 2002's Grand Champion, as the sister of the main character Buddy (Jacob Fisher); and in 2003's Spymate, as the kidnapped daughter of former secret agent Mike Muggins (Chris Potter), who tries to rescue her with the help of a spy monkey. Grand Champion had a brief theatrical release in August 2004, while Spymate was not released until February 2006, when it was given a theatrical run in Canada, followed by its DVD release in April 2006. In August 2003, Roberts was scheduled to shoot an independent film called Daisy Winters, starring as the title character, alongside Rachel Weisz. However, the film, which would have been Roberts' first leading role, never began shooting due to financial problems.
Roberts became a teen idol at the age of thirteen, starring as the lead character Addie Singer in the Nickelodeon series Unfabulous, which debuted in September 2004. While Nickelodeon had wanted to cast her for the role from the beginning, the teen sitcom earned Roberts a Teen Choice Award nomination and several Young Artist Award nominations. The series became one of the network's most-watched programs and was quickly recommissioned for a second season.
As her character on Unfabulous writes songs and plays guitar, Nickelodeon soon considered a career in music for Roberts as well, following the lead of other actress/pop singers such as Hilary Duff and Lindsay Lohan. Roberts first contributed the song "If I Had It My Way" to the soundtrack of Disney's 2005 film Ice Princess. This was followed by her debut album, Unfabulous and More: Emma Roberts, which was released on September 27, 2005 and is featured as the soundtrack to Unfabulous. The album peaked at #46 on the Billboard's Top Heatseekers, and two music videos were released simultaneous to promote the album: "I Wanna Be" and "Dummy".
In 2006, Roberts returned to the big screen, starring alongside Sara Paxton and singer JoJo in Aquamarine. They became good friends while filming. The film about two teenagers (played by Roberts and JoJo) who find a mermaid (Paxton) in their swimming pool, earned Roberts a 2007 Young Artist Award for Best Supporting Young Actress in a Feature Film. Roberts also contributed a cover version of Weezer's 2001 single "Island in the Sun" to the film's soundtrack. Following Aquamarine, she was scheduled to star in Camp Couture (produced by her mother, Kelly Cunningham) and Bras and Broomsticks (based on the book of the same name by Sarah Mlynowski), but neither film went into full production.
On May 15, 2006 Roberts was featured on MTV's Punk'd with pop singer Teddy Geiger. In 2006, Roberts also became a spokesmodel for Dooney & Bourke, and designed her own Dooney & Bourke handbag, named after her.
In early 2006, Roberts finished shooting Nancy Drew, in which she stars in the title role of teen detective Nancy Drew. It was released on June 15, 2007. Roberts has appeared on the cover of the Rolling Stone Magazine
Roberts also starred in the movie Wild Child, about a rebellious teen from Malibu sent to an English boarding school, in London. The movie ended production in late 2007, and was released on August 15, 2008 in the United Kingdom. The movie will be released in the U.S. in November 2008
Roberts is set to be reunited with Nancy Drew director Andrew Fleming on both Rodeo Gal and a Nancy Drew sequel, although the latter has been put on hold. She was also selected for two more projects: James Strouse's high school comedy The Winning Season, alongside Sam Rockwell and Rob Corddry; and the CG-animated holiday feature The Flight Before Christmas with comedian Norm MacDonald, set to be released on October 28.
