Sarah Michelle Gellar's kids must be pretty excited that their mom is joining the cast of "Star Wars Rebels."

Her son, Rocky, and daughter, Charlotte, were photographed wearing matching "Star Wars" Stormtrooper slip-on shoes.

Gellar posted a picture of three pairs of feet wearing the Stormtrooper shoes. Two of the pairs of feet are those of Rocky, 2, and Charlotte, 5. Gellar's feet are the remaining pair. 

"Sometimes you just need to rock matching kicks #StarWars #Stormtroopers The family that dresses together......#SundayFunday," Gellar captioned the photo.

Gellar called daughter Charlotte her "performer," according to E! News.  

"She's my dramatic, definitely all-girl," she added.

Gellar says Rocky is "kind of a goof ball."

"He goes for the laugh, like, the girls in school all love him," Gellar said.

"Sometimes I have to question whether he has any guy friends at school, 'cause he'll come home and he'll talk about Lila, Lily, Scarlett, Poppy ... and I'm like, 'Do you have boy friends? Do you have guy friends?' I'll get all these calls from these moms, like, all these girls asking for playdates with my son and I'm thinking, 'Oh my God, it starts already,'" Gellar added.

Gellar says that Rocky "likes the older ladies." 

"He definitely likes my daughter's friends," she said.  

Gellar is joining her husband, Freddie Prinze Jr. on the show. The animated series takes place in between the third and fourth episodes of the "Star Wars" series.

Gellar will join the show for its second season. The first season was very successful, with more than 49 million viewers tuning in during the season.

"We're thrilled to have Sarah Michelle Gellar on board for season two," executive producer and supervising director of the series Dave Filoni said.

"She is a true 'Star Wars Rebels" fan and her passion undoubtedly comes through in the voice recording sessions," Filoni added, according to E!
