Episode 1 of Matilda and the Ramsay Bunch was released on BBC Iplayer on 29 April 2016 a week before original broadcast.
Matilda and the Ramsay bunch - dad Gordon, mum Tana, big brother Jack and sisters Megan and Holly - touch down in Los Angeles and get very competitive from the word go.
To celebrate arriving in Los Angeles, Matilda cooks an all-American dinner - healthy fried chicken and Hollywood Hills crunch.
As well as cooking, Matilda makes a prank film and the whole family fall for her tricks, even dad Gordon - gotcha!
Matilda is cooking a slap-up pre-concert meal for the Vamps, then together with her brother, sister and their friends they're going to watch the band play live.
Matilda cooks pulled chicken lettuce wraps, rocking Ramsay rice balls and microphone cake pops.
She's not the only one who gets a taste of rock stardom though - Brad and James, the Vamps' guitarists, lend Matilda's brother Jack a guitar and he gets to play on stage with them.
