A schoolgirl can decide whether she wants to be blonde or brunette every morning thanks to a rare genetic 'birthmark' that causes her hair to be two dramatically different colours.
Mum Jenny Hill, from Lincoln, was stunned when 11-year-old Bella was born with a head of half blonde and half brunette hair.
Since then, gobsmacked passersby admire her hair and constantly quiz her about whether she dyes it or not.
Student nurse Jenny, 35, believes that the distinctive trait is caused by poliosis, which creates a lack of pigment in a patch of hair.
The schoolgirl even has different coloured eyelashes - her right lashes are a light colour while her left ones are dark.
Bella's unique barnet means that every morning she can decide whether she wants to embrace her blonde or brunette side depending on the parting - making the decision based on her outfit.
Jenny, from Lincoln, Lincolnshire, said: "It's really different and unique. My mum pointed it out when she was born but at the time I was in too much pain to notice.
"She was saying she's fair and I said she's dark then we noticed her eyelashes were fair on the blonde side and dark on the brunette side.
"I asked about it at her six-week check-up and they kind of just said 'oh yes' and didn't make a big deal out of it.
"As parents it's more noticeable because you stare at your baby but it's more prominent as she's got older.
"In the summer the darker side does go fairer. The blonde is an ice blonde, like it's been bleached and it goes all the way underneath in an unusual pattern.
"If she has it in a certain style, she's blonde but if she changes her parting, she's brunette.
"She prefers her hair lighter when she wears more girly clothes and pastel colours but when she wears her hoodies and joggers, she wears it up so it's dark."
Bella said: "I don't really have a favourite shade, it depends what outfit I'm wearing.
"A lot of school friends do want my hair and some ask if I dye it."
The mum-of-three suspects the rare feature is caused by poliosis as neither of her other children, Riley, 14 or Lilah, four, have inherited it.
Jenny admits that Bella's unique 'do garners a lot of attention with strangers asking if they colour her hair.
Others joke that Jenny 'must have inhaled a lot of bleach' while working as a hairdresser when pregnant with her.
Jenny said: "We got a lot of attention when she was little.
"It would take us hours to get round the supermarket because people would stop and admire Bella's hair or ask if we'd dyed it.
"I was a hairdresser when I was pregnant with Bella so it was a running joke that maybe I'd been around the bleach too much.
"A lot of people don't notice her eyelashes but it's obvious when you look at her.
"She gets told by everyone that she isn't allowed to touch her hair.
"We've only ever seen similar hair once. We were in the supermarket once and we saw another boy with a patch of hair like Bella's.
"It was really exciting. Bella pointed him out and said 'he's got hair like me' so we went over because we haven't seen anyone else before."
