MEET Millie Innes, the cute as a button young Scottish actress who is the star of a brand new eponymous BBC television show.

The 13-year-old from Cardonald, Glasgow, has been cast in the lead role in CBBC comedy series, Millie Inbetween, which starts on Wednesday. It charts the growing pains of blended family life for the fictional Millie and her older sister Lauren after their parents split up.

Ms Innes, who has previously had roles in dramas Case Histories and Single Father, landed her own show after first impressing BBC bosses when she auditioned for a part in the Tracy Beaker spin-off series Dani's House three years ago, beating 20,000 youngsters to the role of Maisy.

Millie Inbetween, which was filmed over the summer at the River City studios in Dumbarton, looks set to make the teenager a household name, but Ms Innes is keeping both feet planted firmly on the ground.

"A few of my close friends know about the show but I don't tend to talk about it in school," she says. "Some of my teachers suggested we should do something to celebrate, but I told them I'd prefer not to. People will find out about it in their own time. I don't want to be seen to make a fuss, brag or show-off.

"We don't make a big thing of it as a family," she adds. "It's such a normal thing for me now and just like any other person going out to get a weekend job in Sainsbury's."

Ms Innes, who is in third year at Ross Hall Academy and attends the Glasgow Academy of Musical Theatre Arts, lives with her parents, Julia, 41 and Campbell, 50, and younger brother Murray, five.

By the time she was two, such was her burgeoning passion for acting and dancing that her father built a small, wooden stage in her bedroom. While still at primary school, Ms Innes won parts in cBeebies shows Nina and the Neurons and Me Too! before landing her breakthrough role in Single Father opposite David Tennant when she was nine. Most recently she played the daughter of Jason Isaacs in popular crime drama Case Histories.

She may share a name with her on-screen alter ego in Millie Inbetween, but Ms Innes is keen to emphasise that it is a character she plays. "I was anxious about Millie being perceived as me and the real Millie," she says. "I was able to have a say in what she is like, though. I would describe her as quirky and the boss of the house. When things go wrong, everyone looks to her."

Ms Innes admits to rarely watching her own acting performances afterwards, saying that as perfectionist she would only pick them apart. "Millie Inbetween was a bit different," she says. "We had a screening for it, so I was forced to sit through an hour and a half of my face on a big cinema screen. I don't watch myself usually because I'm my worst critic and always think: 'I could have done that a bit better' or 'why did they choose that take?'"

Away from acting, she enjoys going to concerts and having sleepovers with her friends. Her favourite subject at school is English, one which Ms Innes hopes to study at Oxford University when she is older. Pursuing an acting career, however, remains her main ambition. "My dream job would be a gritty Hollywood movie similar to what Natalie Portman did in Leon when she was around my age," she says.

Her mother Julia confirms that from an early age the signs were there that her daughter was destined for a thespian's life. "When Millie was six or seven, she loved the Tracy Beaker show," says Mrs Innes. "It used to drive myself and Campbell insane, hearing the title music over and over as she watched all the repeats. One day we were sitting on the sofa with Millie sandwiched between us, wearing her tutu and high heels, and she said: 'I'm going in a show like that one day, I promise you.'"

Millie Inbetween starts on CBBC on Wednesday at 5pm
