Happy National Kissing Day!

It's time to grab your SO (or just the person closest to you) and plant a kiss on them all in the name of celebrating this wondrous holiday. After all, do we really need a reason to show a little extra PDA? And when it comes to flaunting a little love, no one does it better than Chrissy Teigen and her hubby John Legend. They might just be one of the most adorable couples in Hollywood.

Sure, it takes guts to open up about your feelings in public, but imagine baring your soul in a song for millions to hear. John penned "All of Me" for his love — forever setting the bar entirely too high.

"The more you know someone, the more you’re inspired by your relationship," John explained to Los Angeles Confidential in 2015. "Also, I grew up just learning what it means to be in love with somebody… because I had never really been in love before. I guess you have to grow enough to be able to write that song with sincerity and authenticity."

Chrissy is also notoriously candid when it comes to discussing the private details of her relationship. She even admitted that they started dating after hooking up on set.

"I pretended not to care," Chrissy told Wendy Williams in 2014. "We did the music video, we were together for 12 hours. This was eight years ago. And then we spent this entire day together, me in my underwear, him in a full suit. I went to go say goodbye to him at his hotel, and I just didn't ever say goodbye that night."

Take a cue from John and Chrissy and don't be shy about your feelings (at least on this holiday).
