7-Year-Old 'Avengers: Endgame' Actress Makes Plea for People to Stop Bullying Her

"Hi, I'm Lexi Rabe, I'm 7 years old, and I mess up sometimes," she says in a video posted to Instagram.

The youngest actress in "Avengers: Endgame" is making a plea for people to stop bullying her online.

In a video posted to her Instagram account, she admitted that sometimes she makes mistakes.

"Hi, I'm Lexi Rabe, I'm 7 years old, and I mess up sometimes," the video begins.

Lexi plays the daughter of Robert Downey Jr.’s character, Tony Stark, in the smash-hit film. In an interview on ABC’s "Good Morning America," Lexi and her mother, Jessica, said they were recently at a Los Angeles mall when a fan who recognized her got upset that she wouldn’t snap a picture. 

They both said that fan took their anger out toward them online.

"I don't know why you need to get mad at us because we're not available. We're normal people we have busy lives like everybody else," Jessica said.

In the Instagram video's caption, Jessica, who runs her daughter's account, said they try to appease everyone when they can. 

“Sometimes we're rushing from place to place stressed like everyone else to get to set on time or work or whatever and we seem a little grumpy,” the caption reads in part.  “I’m sorry if you see us this way but that’s life!

"If you ask us for an autograph we almost always say yes. If we happen to be having a bad day that might put us right on the right! We are not perfect! These perfect children are not being given the freedoms and the rights that they should.”

A follow-up post on Lexi’s account features a picture of Downey as Stark along with the message, “Protect a child. Say no to bullying! Stay off our page if you’re a bully!”

At the end of her original video, Lexi sums it up best with her signature line from the film.

“I'm just 7 years old. Please don't bully my family. Or me. Bye. Love you 3,000," she says.
