Zoe Salmon has leapt into her new role as the 30th person to become a presenter on TV show Blue Peter.
The 24-year-old will take over from current presenter Liz Barker while she has a baby, and then will stay on the team when Liz comes back.
Zoe said: "It's been the biggest secret I've ever had to keep and it will be a major relief to my friends and family.
"I'm so excited and I'm really looking forward to all the mad stuff I know they throw at you on Blue Peter."
Zoe has just started filming for the programme, but won't be seen on screen until the 23 December in the Christmas musical spectacular.
She got the job after answering an advert that didn't say what the job was, so she didn't know it was Blue Peter she was applying to.
After lots of interviews she had to pass a final audition - a mini programme which included interviewing someone on a trampoline.
