Rachael Ray was ''nervous'' about appearing in 'Gilmore Girls: A Year in the Life'.
The 48-year-old television chef makes a cameo appearance on the Netflix reboot of the classic drama series when she's drafted in to work at the fictional Dragonfly Inn whilst Sookie - played by Melissa McCarthy - is out of town.
Speaking to 'Entertainment Tonight', the '30 Minute Meals' host said: ''I was so nervous. I mean, I'm not an actress.
''Everything we do is unscripted, but I was so impressed that the food stylist made all my food...She made all my real food, so it was kinda cool!''
Rachael's character finds herself getting fired from the fictional kitchen, and whilst she was ''embarrassed'' to be let go, she's glad it meant Melissa, 46, could reprise her role.
She added: ''I've only been real-fired once in life, and I was kind of embarrassed that I got fake-fired on the show, but if it brought back Melissa McCarthy, that's fine with me.''
Despite feeling nervous before stepping onto the film set, Rachael said 'Gilmore Girls' veteran Lauren Graham - who plays Lorelai on the show - helped her ''feel at ease''.
She said: ''Lauren I've known for years, she's one of our favourite guests [on 'The Rachael Ray Show'], and I just think she's such a delight to be around.
''She makes everybody feel at ease. She's so lovely and a great actress, [and she] calmed me right down on set!''
Meanwhile, the celebrity cook said keeping her cameo appearance a secret was easier than she expected, as people only ever asked her questions about her work on cooking shows.
She revealed: ''I work all summer over at Food Network. People just ask me food questions, so it was pretty easy to keep it a secret.''
