Ariana Grande promoAriana GrandeAriana Grande might be just 21 years old but she’s a;ready had sucres as both an actress and singer. Her first big break break came when she was cast as Cat Valentine in Nickelodeon series 'Victorious' in 2011. She then landed her own spin off series, Sam and Cat alongside ‘iCarly’ star Jennette McCurdy, which latest for just one season. However by the time she’d landed her own sitcom, Grande had also made the move into music. She released her debut album Yours Truly in 2013 to critical acclaim, but Ariana would become a fully fledged pop star this summer with the success of single 'Problem' from her upcoming second album. Becoming one of the summer's biggest hits, 'Problem' reached number one on the UK Singles Chart and number two on the Bllboard Hot 100.

Zooey Deschanel promoZooey DeschanelGiven how her career has evolved, it’s fitting that Zooey Deschanel first came to our attention after her role in Almost Famous, a movie about music. Since finding fame as an actress, the future ‘New Girl’ couldn't help showing off her vocal talents wherever possible, in films such as Elf and 500 Days of Summer. But in 2007 Zooey officially made the move into music when she formed the band She & Him with musician M.Ward. So far the indie duo have released four albums, including 2011’s festive offering, A Very She & Him Christmas. Last month the duo hit the big time when they signed a new record deal with major label Columbia Records, ahead of their fifth album’s release later this year.

Juliette Lewis promoJuliette LewisProbably not the first woman who's going to pop into your head when you think of actresses turned singers but, after her Academy Award nomination following her role in Martin Scorsese's 'Cape Fear' remake back in 1991, it seemed a screen career just wasn't enough for budding rocker Juliette Lewis. After further blockbusters such as 'Natural Born Killers', 'From Dusk till Dawn', 'The Evening Star' and 'Starsky & Hutch', she released her debut album '...Like a Bolt of Lightning' in 2004 alongside her band Juliette And The Licks. She proceeded to release two more over the next consecutive years and made her last record, 'Terra Incognita', in 2009. She's back to acting now, but we wouldn't be disappointed to see another musical venture.

Taylor Momsen promoTaylor MomsenAnother actress who invoked her inner rock goddess was 'Gossip Girl''s Taylor Momsen, whose early acting role in 2000's 'Dr. Seuss' How the Grinch Stole Christmas' would never have suggested a heavily eyelinered and scantily clad future. Her success as the lead singer in The Pretty Reckless has been phenomenal as of late, with her March 2014 album 'Going to Hell' reaching the top 5 in the US album chart - quite a remarkable progression since they started out in 2010. However, we are still missing her face on our TV screens and awaiting at least a temporary screen comeback.
