f(x) rapper Amber Liu got together and grabbed some tasty burgers with the popular YouTube crew JustKiddingFilms while she was visiting her home state of California recently.

Amber and several JustKiddingFilms crew members trooped to a burger joint called Grill 'Em All where the idol ordered a huge burger meal, which revealed her crazy appetite for American food.

Known for her friendliness, Amber had a great time hanging out with and eating burgers with the JustKiddingFilms crew.

Amber even got into a cute eating challenge with one of the members.

YouTube commenters were amazed again at the wide circle of friends that Amber seems to have.

"I'm pretty sure the only person Amber hasn't met in this Earth is me," "Amber! My gosh she's everywhere. Is there a person Amber does not know?" said two fans in the comments section on the YouTube video.

Amber is famous for her large number of friends not only among other K-Pop groups - which was made evident in the numerous cameos in her debut song "Shake That Brass" - but also among overseas personalities.

"Amber is close to YouTubers. She did some videos with EatYourKimchi too," said another YouTube commenter.

In other news, Amber recently became an endorser for Talent Cosmetic where she shot a commercial and applied makeup, showing her feminine side.
