Rihanna was born in Saint Michael, Barbados on February 20, 1988, to Ronald Fenty, a warehouse supervisor, and Monica Fenty, an accountant. Her mother, a native of Guyana, is Afro-Guyanese, and her father is of Barbadian and Irish descent. She is the oldest of three siblings; two younger brothers, Rorrey and Rajad Fenty. She began singing at around the age of seven. Her childhood was deeply affected by her father's addiction to crack cocaine and parent's rocky marriage, which ended when she was fourteen years old. Rihanna attended Charles F. Broome Memorial School, a primary school in Barbados, and then the Combermere School, where she formed a musical trio with two of her classmates at the age of fifteen. In 2004 she won the Miss Combermere Beauty Pageant. She was an army cadet in a sub-military programme that trained with the military of Barbados and Shontelle was her drill sergeant. Rihanna's musical style has changed during the release of her last three albums. She was originally marketed as a reggae singer since she burst on scene in 2005, with a styles of pop, R&B and dancehall. With the release of her debut album Music of the Sun and its lead single "Pon de Replay", Jason Birchmeier of Allmusic described Rihanna's musical style as "synthesize Caribbean rhythms and beats with standard-issue urban dance-pop: Caribbean-inflected urban, if you will." Rihanna is also described as utilizing "dancehall-lite beats and a reggae vocal cadence." Barry Walters of Rolling Stone considers Rihanna's A Girl Like Me to be "lightweight dancehall and R&B jams." After the release of Good Girl Gone Bad, Allmusic's Andy Kellman credits Rihanna to be "as pop as pop gets." Kelefa Sanneh of The New York Times described her hit "Umbrella" as a lightweight pop confection with a heavy hip-hop backbeat, a breezy love song enriched by those unexpectedly goth-sounding keyboards and by the incongruous hint of anguish in Rihanna’s girlish voice. Her debut album featured a refreshing touch from pop veterans Evan Rogers and Carl Sturken of Syndicated Rhythm productions, who first discovered her. Carl Sturken and Evan Rogers have collaborated with Rihanna many times, including with her debut single "Pon de Replay", which helped launch her career with the tradition of reggae and dance pop and also collaborated on her sophomore album. Rihanna then enlisted into the pop and contemporary R&B working with music producer Stargate and singer-songwriter Ne-Yo on "Unfaithful" and sampling the key section, bass line, and drum beat from Soft Cell's 1981 single "Tainted Love" on "SOS". One of Rihanna's major influences and idols is Mariah Carey, whose song "Hero" she covered while performing at a school talent show. She says, "I looked up to [Mariah] a lot and I still do. I admire her as an artist, and to [compete with her] was a moment I will never forget for the rest of my life. Rihanna also considers Madonna as one of her biggest influences and said that she wants to be the "black Madonna". She mentioned that she respects Madonna's ability to reinvent herself and aspires to be just as successful. Beyoncé Knowles has also been named as her major influence, citing that she was inspired to start her career after watching Knowles on television as part of a Destiny's Child performance . Her other musical influences include Bob Marley, Alicia Keys, Whitney Houston, Destiny's Child, Celine Dion, Brandy, and Gwen Stefani. The New York magazine described Rihanna's early look as a cookie-cutter teen queen and that she has the ability to shift looks so dramatically and with such ease. Since the release of her third album, Good Girl Gone Bad, [Rihanna's] has become a sex symbol and also set herself apart from other R&B starlets, opting for designer couture over belly-baring crop tops. Sonya Magett of Black Voices reported that Rihanna's style has become quite risqué since she burst on the scene 4 years ago. In 2008, she constantly surprised, switching from pretty and sweet in pastels on the red carpet to dominatrix-leaning wear on stage and at awards shows. Rihanna's fashion and style also landed her on the list of People's 10 Best Dressed Stars of 2008. Glamour also awarded Rihanna with the seventeenth most glamorous woman of 2009 out of fifty. Glamour also commented on Rihanna's style saying "rockstar of leading ladies" and "She almost can’t make a style mistake right now.” They also said her "little-bit-punky, very-much-girly look still entrances readers." Rihanna's tattoos have drawn much media attention. She has a total of twelve known tattoos, including a music note tattoo on her ankle, a Pisces sign behind her right ear, a Sanskrit prayer going down her hip, a star in her left ear, the word "love" on her left middle finger, an Arabic phrase on her ribcage area, meaning "Freedom is God", a trail of stars going down the back of her neck, a skull with a pink hair bow, the phrase ’shhh...’ on her right index finger, the date ‘11.4.86? on top of her left shoulder and a henna-style dragon claw, complete with Hawaiian hibiscus flowers
