HOT! Miley Cyrus and Cody Simpson are obviously the sexiest couple in Hollywood right now -- and we say right now because who knows how long they can keep this up!

We can't help but think something this fast and intense just can't last, but for now, we are THERE for it! Miley and Cody enjoyed a romantic sushi dinner date Friday night and then took a stroll to get some ice cream and literally ALL the way there, they made out. The walked and stopped and kissed and walked and stopped and hugged and walked and stopped and made out and ... well, you get it.

No one ever claimed Miley was a shrinking violet or not one to jump head first when it comes to relationships. She was all-in on gal pal Kaitlynn Carter after her split from estranged hubby Liam Hemsworth but it didn't take her long to move on to Cody. And now fans are speculating the two have already moved in together as Cody posted to social media a pic captioned "move-in day" earlier this week.

These two are SERIOUS!
