Jon Bon Jovi addresses age question about his son proposing to 19-year-old Millie Bobby Brown

Jon Bon Jovi has finally addressed the question that has been on a lot of people's lips since his son's big announcement.

The world was seemingly overjoyed when Millie Bobby Brown revealed she and her boyfriend, Jake Bongiovi, were engaged.

The happy couple dropped the news on social media, with the Stranger Things star writing: "I've loved you three summers now, honey, I want 'em all."

While they were quickly flooded with congratulatory messages, it didn't take long for people to question the engagement.

According to Pop Sugar, some critics argued Millie and Jake are too young to be getting hitched, as they are 19 and 20 years old, respectively.

One person wrote on Instagram: “Unpopular opinion but she’s way too young to be engaged. But age 19, you don’t even know who you are yet."

Another added: “Look, they seem cute, but she’s 19 right? They’re too young to be getting engaged, WTF?”

A third said: "Sorry to be a killjoy but this is not going to last, millie you grew up too fast, you deserve a normal and fun adolescence. You are 19."

They added that the two have only been dating for less than two years and should've waited a little longer.

However, it seems like the happy couple has been given the big tick of approval from Jake's rockstar dad.

He was asked about the topic when speaking on Andy Cohen Live and said: "I don’t know if age matters if you find the right partner and you grow together.

"That would be my advice: Growing together is wise. So, I think all my kids have found people that they think they can grow together with, and we like them all."

Jon added: "Millie’s wonderful. Her whole family are great. Jake is very, very happy.”

Now, that's how you shut down the haters.

Who is anyone to judge if two people are happy and feel confident in their plans and life goals.

Time is completely relative and if Jake and Millie want to get married then they are completely free to do so.

Funnily enough, after the Stranger Things star made the big announcement, fans dug up a comment Ariana Grande made that referenced how her upbringing was very different.

Commenting beneath a 2018 post of Millie, who was 14 at the time, kissing her former flame Jacob Sartorius atop a lifeguard watchtower on the beach captioned 'moonlight with him', Ariana quipped: "I wasn't even allowed to leave my house until I was 20."
