Sarah showed off shimmery gold eye shadow and a bit of mascara in the close-up shot, in which she sported white, clearly emulating the original Star Wars heroine - played by Carrie Fisher.

In the caption for her post, the mother-of-two also gushed: 'I'm super excited to announce that I will be on the #StarWarsRebels panel at #NYCC on 10/8, 1:30pm, on the Empire Stage (of course). Hope to see you there! #StarWars @starwars.'

The former Buffy the Vampire Slayer star is a recent addition to the cast - which already includes her husband - Freddie Prinze Jr. - and David Oyelowo.

The casting was announced by Disney XD in March, with executive producer Dave Filoni adding that Sarah 'is a true ‘Star Wars Rebels’ fan, and her passion undoubtedly comes through in the voice recording sessions.'

'Shhhh!' Sarah gushed: 'The #force was definitely with me,' beside this snap, in which it appears she had been working on her new role for the upcoming second season of Star Wars Rebels

The series, which reached more than 49 million viewers in its first season, takes place between episodes III and IV of the Star Wars saga, and follows the crew of the starship Ghost as they attempt to evade the growing Empire and its agents, as reported by Variety.

Sarah, who frequently shares her love for the Star Wars franchise on her Instagram account, has taken to teasing the upcoming role since the news in March.

At the end of August she posted a snap of her posing in front of computers running what appeared to be editing software as she held her finger up to her lips.

Like mother, like daughter: It seems the former Buffy the Vampire Slayer star has passed her tastes down onto her children, as in this snap she joked that it was clear which backpack was her daughter's, the Star Wars Rebels one

'Shhhh don't tell anyone what I was doing today- it's a secret #StarWars #StarWarsRebels The #force was definitely with me,' she captioned the photo.

The doting mom then showed she may have passed her passion for the series down to her children as she shared a snap of her daughter's back-to-school gear.

Alongside a picture of a shelf full of backpacks - including a Star Wars Rebels-themed bag - Sarah wrote: 'One guess which backpack is my daughters? #starwars #starwarsrebels #backtoschool.'

Sarah will be appearing at New York Comic Con to promote Star Wars Rebels on October 8, and the second season for the Disney XD series will premiere Wednesday, October 14 at 9:30pm.
