Millie Bobby Brown's parents are under fire for allegedly letting their 16-year-old daughter date a 20-year-old. Fans on Twitter are calling them out for perpetuating an inappropriate relationship and subjecting their daughter to predatory behavior.

In the past, the Stranger Things actor was linked to the famous TikToker Hunter Echo. However, not much information about their relationship has been publicized. They are expected to be broken up as Echo was talking about their relationship in the past tense and Brown is rumored to be dating Jon Bon Jovi's son, Jake Bongiovi.

Fans were left seething when Echo, 21, went live on Instagram, sharing explicit details about his intimate life with Brown, 17. Many believe that the two were dating while Brown was a minor and he was an adult.

One supporter tweeted, "This is literally grooming? We don't need to know the full situation. Millie's parents and Hunter are in the wrong. End of story."

Another wrote, "A 20-years-old dating a 16-years-old kid. Where were her parents? Who allowed their “relationship”? And the most important thing: Why didn’t these photos come out earlier? I’m disgusted and not surprised at how wrong this world can be. SHE. WAS. A. KID."

Other fans have been adding fuel to the fire, mentioning that Brown's parents have been "using her for her money," while mentioning the high-figure salaries she brought home for Stranger Things and Enola Holmes.

As reported by Newsweek, Echo lashed out against those calling out the inappropriate nature of his relationship with Brown. He said, on camera: "You guys don't know anything. You guys are just following after one person saying one thing, like, everybody hates him so that everyone's going to hate me."

He continued to say that he wouldn't apologize and that Brown's parents condoned the relationship. Echo shared, "I was living at Millie's house for eight months. How the f*** is that a lawsuit? I thought her mom and dad knew about everything."

In response, fans are taking to their social media platforms to demand that Echo and Brown's parents take accountability for their actions. Many are stating that Brown's parents are irresponsible and don't deserve custody of their children, as Brown also has a younger sibling.

One fan tweeted, "Millie Bobby Brown's parents shouldn’t even have custody, they let a 20-year-old date their 16-YEAR-OLD KID. They just care about money, they’ve forced her to work since she was like 9 cause they were broke."

As of now, Millie Bobby Brown has not released a statement about the drama.
