Carlos PenaVega and Alexa PenaVega are literally the definition of #RELATIONSHIPGOALS but was Carlos seen kissing another woman?! Yes…but don't freak out just yet because it's not what you think!

Carlos plays Kenickie in Fox's live musical telecast, Grease: Live alongside Vanessa Hudgens who was cast as Rizzo. These two have a smooching scene and Carlos recently opened up about what it was like to practice doing something that is so unfamiliar to him!

"Our first time in rehearsal, I'm like, 'Do we just start kissing off the bat? Like, how does this work?', he said. "We're like running the show through in our rehearsal space … I was like, 'Oh my gosh! We have to do the whole kissing scene' … so then it comes to our scene, and her and I are, like, sitting there. I started to go in, and I just didn't feel right."

Oh no! We're thinking he'll get the hang of it!

Carlos continued, "So I was like, 'Okay, cool, so we're not doing this.' So I just kissed her neck." LOL!

There you have it! Carlos is as loyal to Alexa as always yet he's a hard worker and takes his roles very seriously! We can't wait to see him, Vanessa and the rest of the cast when Grease: Live airs on Sunday at 7 p.m. ET on FOX.
