One month later, she made her debut on the Grand Ole Opry. Also in 2000, she toured with Trisha Yearwood. Heart Shaped World also produced two more Top 40 country singles in "You Go First (Do You Wanna Kiss)" and "Unbreakable Heart", although the fourth single ("I Do Now") failed to reach Top 40. The album itself peaked at No. 24 on the Top Country Albums charts. Andrews was also featured on the premiere episode of On the Verge, a television series on CMT which followed the careers of up-and-coming country artists. On May 3, 2000, Andrews was invited to sing "Unbreakable Heart" at the 2000 Academy of Country Music awards, where she won the award for Top New Female Vocalist. Who I Am Who I Am was the title of Andrews' second album, released in 2001. It was used as the theme song for the police drama Sue Thomas: F.B.Eye where the main character Sue Thomas (played by deaf actress Deanne Bray) was a deaf FBI officer, landing a position in an FBI Surveillance team thanks to her lip reading skills. It also appeared at the end of an episode of Lizzie McGuire. Andrews, who was 17 years old when Who I Am was recorded, described the album as a more mature effort than Heart Shaped World, because it focused more on the emotions that come with growing up. Serving as the album's lead-off single, "Who I Am" became, to date, Andrews' only Number One (and only Top Ten) hit on the country music charts, in addition to peaking at No. 28 on both the Billboard Hot 100 and Hot Adult Contemporary Tracks charts. In a 2001 interview, Andrews explained that she recorded the song (which was written by Brett James and Troy Verges) because she felt that its lyrics were especially fitting to her own life: "Everything is so true in that song, except that my grandmother's name is not Rosemary. It's about believing in yourself and being supported by those around you. No matter how many mistakes you make, your friends and family will be there for you." Also included on the album was Andrews' first songwriting credit in the track "Good Friend to Me", which she co-wrote with Annie Roboff and Bekka Bramlett. Andrews spent 2001 on tour with Billy Gilman to help promote her second album and its lead-off single; she later toured with Tim
