Lab Rats star Kelli Berglund has been dating actor Sterling Beaumon since the end of December (at least, that's when she first went public with their relationship) and they couldn't be cuter together! The couple is always posting adorable photos with sweet messages on both Instagram and Twitter, and apparently they even have fun nicknames for each other!

On New Year's Eve, Kelli shared a pic with Sterling and captioned it, "2014: you were a roller coaster ride. Timeless memories with people who have been in your life forever, or maybe even walked in unexpectedly. 2015: I hope you're a year of good fortune & great love."

Aww! We obviously couldn't resist making them our Couple of the Week!
