Doris Mary Ann Kappelhoff was born on April 3, 1922, in Cincinnati, Ohio, the daughter of Alma Sophia (nee Welz), a housewife, and William Joseph Kappelhoff, a music teacher and choir master. All of her grandparents were German immigrants. For most of her life, Day reportedly believed she had been born in 1924 and reported her age accordingly; it was not until her 95th birthday, when the Associated Press found her birth certificate, showing a 1922 date, that she learned otherwise. The youngest of three siblings, she had two older brothers: Richard (who died before her birth) and Paul, 2-3 years older.
While recovering from an auto accident, Day started to sing along with the radio and discovered a talent she did not know she had. Day said: "During this long, boring period, I used to while away a lot of time listening to the radio, sometimes singing along with the likes of Benny Goodman, Duke Ellington, Tommy Dorsey, and Glenn Miller [...]. But the one radio voice I listened to above others belonged to Ella Fitzgerald. There was a quality to her voice that fascinated me, and I'd sing along with her, trying to catch the subtle ways she shaded her voice, the casual yet clean way she sang the words." Observing her daughter sing rekindled Alma's interest in show business, and she decided to give Doris singing lessons. She engaged a teacher, Grace Raine. After three lessons, Raine told Alma that young Doris had "tremendous potential"; Raine was so impressed that she gave Doris three lessons a week for the price of one. Years later, Day said that Raine had the biggest effect on her singing style and career. During the eight months she was taking singing lessons, Day had her first professional jobs as a vocalist, on the WLW radio program Carlin's Carnival, and in a local restaurant, Charlie Yee's Shanghai Inn. During her radio performances, Day first caught the attention of Barney Rapp, who was looking for a girl vocalist and asked if Day would like to audition for the job. According to Rapp, he had auditioned about 200 singers when Day got the job. While working for Rapp in 1939, she adopted the stage surname "Day", at Rapp's suggestion. Rapp felt that "Kappelhoff" was too long for marquees, and he admired her rendition of the song "Day After Day". After working with Rapp, Day worked with bandleaders Jimmy James, Bob Crosby, and Les Brown. While working with Brown, Day scored her first hit recording, "Sentimental Journey", released in early 1945. It soon became an anthem of the desire of World War II demobilizing troops to return home. This song is still associated with Day, and she rerecorded it on several occasions, including a version in her 1971 television special. During 1945-46, Day (as vocalist with the Les Brown Band) had six other top ten hits on the Billboard chart: "My Dreams Are Getting Better All the Time", "'Tain't Me", "Till The End of Time", "You Won't Be Satisfied (Until You Break My Heart)", "The Whole World is Singing My Song", and "I Got the Sun in the Mornin'". In the 1950s she became the most popular and one of the highest paid singers in America.

how old was she at this time?

Wonder Girls (Hangul: weondeogeolseu) was a South Korean girl group formed by JYP Entertainment. The group's final line-up consisted of Yubin, Yeeun, Sunmi and Hyerim. Members Sunye and Sohee officially left the group in 2015, while Hyuna left in late 2007. They were co-managed in the United States by Creative Artists Agency.
After Park Jin-young revealed the name of his first girl group Wonder Girls in May 2006, the Wonder Girls were introduced through a TV show titled MTV Wonder Girls. The first four episodes outlined the characteristics and profiles of each member. Shortly after selecting Yeeun as the fifth member, the Wonder Girls held their first showcase in the MTV Studio. They performed a cover version of "Don't Cha" by the Pussycat Dolls as well as original songs, including "Irony" and "mianhan maeum" ("It's Not Love"). Sunye sang her version of Destiny's Child's "Stand Up for Love", while Hyuna performed a showcase of her dancing skills. The other three members--Yeeun, Sunmi and Sohee--performed a cover version of Janet Jackson's "Together Again". The Wonder Girls officially debuted in early 2007 on MBC's Show! Music Core, performing "Irony", the hip-hop single from their first album, The Wonder Begins. The album sold 11,454 physical copies in 2007. Shortly after, "Wonderfuls", the official Wonder Girls fanclub, was established. The group held several showcases in China after receiving Chinese lessons. In mid-2007, however, members of the Wonder Girls were beset by various injuries and health problems. On June 25, Sohee was sidelined for a month after tearing a knee ligament in a fall from a running motorcycle during the filming of her movie, ddeugeoun geosi joha (I Like It Hot). The remaining four members continued performing until late July, when Hyuna was withdrawn from the group by her parents due to their concern over her problems with chronic gastroenteritis and fainting spells. In autumn 2007, the talent agency Good Entertainment sent their trainee Yubin to JYP Entertainment as a replacement for Hyuna. She made her debut three days later in the group's live performance of "Tell Me" on Music Bank. Their first full-length album, The Wonder Years, was released the following week with "Tell Me" as the lead single. Due to the last-minute addition of Yubin, the album version does not contain her part. However, the performance version of the song was reworked to include a bridge with rapping by Yubin. The single was a hit and reached number one on various Korean television and internet music charts, including KBS's Music Bank. The song also became a number one hit in Thailand. The choreography for the song was simple and widely imitated: by October, many fan performances of the dance circulated on video sharing sites such as YouTube and Daum, including one by a group of policemen who were eventually profiled on SBS's Star King. The dance's popularity was immense and the explosive attention it received became widely known as the "Tell Me Virus", earning the group the title of "Nation's Little Sisters". The Wonder Girls had an extensive promotional schedule for their album, and in late 2007 they began performing their second single, "i babo" ("This Fool"). MTV also began broadcasting The Wonder Life, a reality TV series starring the girls.
