Question: Gwen Renee Stefani (; born October 3, 1969) is an American singer, songwriter, fashion designer, and actress. She is a co-founder and the lead vocalist of the band No Doubt that experienced major success after their breakthrough studio album Tragic Kingdom (1995) along with various successful singles, including "Just a Girl"

Throughout her career as a solo artist, Stefani has won several music awards, including one Grammy Award, four MTV Video Music Awards, one American Music Award, one Brit Award, and two Billboard Music Awards. With No Doubt, she has won two Grammy Awards. In 2005, Rolling Stone called her "the only true female rock star left on radio or MTV" and featured her on the magazine's cover. Stefani received the Style Icon Award at the first People Magazine Awards in 2014. Additionally in 2016, the singer was honored at the Radio Disney Music Awards with a Hero Award, which is given to artists based on their personal contributions to various charitable works.  Stefani has been referred to as a "Pop Princess" by several contemporary music critics. In 2012, VH1 listed the singer at the number thirteen on their list of "100 Greatest Women in Music". Stefani's work has influenced a number of artists and musicians including Hayley Williams of Paramore, Best Coast, Katy Perry, Kesha, Marina and the Diamonds, Stefy, Rita Ora, Sky Ferreira, and Cover Drive. The latter group, a quartet of Barbados musicians, claimed that both Stefani and No Doubt had helped influence their music, to which the lead singer of the group, Amanda Reifer, admitted that she would "pass out" if she were to ever meet Stefani.  The lead single from Love. Angel. Music. Baby., "What You Waiting For?", was considered by Pitchfork to be one of the best singles by Stefani, and would later place it at number sixteen on their "Top 50 Singles of 2004" list. Additionally, "Hollaback Girl" from the aforementioned album would go on to be the first song to digitally sell an excess of one million copies in the United States; it was certified platinum in both the United States and Australia, and peak at number forty-one on Billboard's decade-end charts for 2000-09. Since its release in 2005, "Hollaback Girl" has been called Stefani's "signature song" by Rolling Stone.

Question: Mental As Anything are an Australian new wave/pop rock band that formed in Sydney in 1976. Its most popular line-up (which lasted from 1977-1999) was Martin Plaza (birth name Martin Murphy) on vocals and guitar; Reg Mombassa (birth name Chris O'Doherty) on lead guitar and vocals; his brother Peter "Yoga Dog" O'Doherty on bass guitar and vocals; Wayne de Lisle (birth name David Twohill) on drums; and Andrew "Greedy" Smith on vocals, keyboards and harmonica.

During the sabbatical, Mental As Anything still played short tours and one off gigs, but by 1993 they were back on record, providing the song "Ride", produced by Tim Farriss, for the soundtrack to the Yahoo Serious film Reckless Kelly. They released a compilation of rare album tracks and b-sides, Chemical Travel, in November.  By mid-1994 the band had recorded an album's worth of self-produced material but were having difficulty getting a release deal. They self-released an EP of songs, Bicycle, and gave it away on their summer 1994/95 tour of NSW and Queensland. Radio station Triple J received a copy of the Bicycle EP on Christmas Day 1994 and put the lead track "Mr Natural" on immediate heavy rotation. Other stations followed and the demand led to the track being given a commercial release as a single and reaching the top 30 on the ARIA Charts (although charting higher in the States where the tour and free EP didn't reach). The resulting album, 1995's Liar, Liar Pants on Fire, reached the top 40, with Mombassa's cover taking the 'Best Cover Art' award at the 1996 ARIA Music Awards.  Three further singles were lifted off Liar Liar in 1995 and 1996: Mombassa's "Nigel" which just failed to chart, a cover of Wreckless Eric's "Whole Wide World" which landed just out of the Top 50 (Top 30 in Victoria) and O'Doherty's tribute to Ms Faithful, "Marianne", which was released as the band supported Chris Issak on his 1996 tour of Australia.  On 16 August 1997, Mental As Anything celebrated 20 years together with the same line-up with a free birthday show at the Hopetoun Hotel in Sydney. Late 1997 saw the band put together their third group art exhibition, Mentals III, which was opened by former Prime Minister, Gough Whitlam, at the Manly Art Gallery (Paul Keating had opened their second group exhibition in 1990). Their 21st anniversary in 1998 was marked with the release of the last album by this line-up, Garage, which did not reach the top 50, nor did the two singles lifted from it, "Just My Luck" and "Calling Colin". December 1999 saw the release of Best of Mental As Anything which was accredited by ARIA with a gold certificate by 2001, and a seasonal single "White Christmas", that was given away at their "Yule Party" gig at Sydney's Metro Theatre.
