Nashville'syoungest star Maisy Stella recently sang on-camera for the first time without her sister, but one first she's not ready for? Kissing!

Scoop on Nashville's finale and more!

Maisy and her sister Lennon recently stopped by to perform and chat about their new children's book In the Waves --yes, they wrote a book. When the topic of their ABC series came up, the conversation turned to Lennon's first on-camera makeout with Colt (Keean Johnson). Blushing about this week's episode when Deacon (Charles Esten) found Maddie and Colt getting dressed following, well, something happening, Lennon tells us she refused to let her entire family watch it. Eleven-year-old Maisy, meanwhile, was totally OK with that. Watch the video above to see her get completely grossed out by the whole thing and proclaim that she'll never have her first kiss on camera. Warning: They're adorable.

Make sure to check back for more videos with the Stella Sisters!

Nashville airs on Wednesdays at 10/9c on ABC. Check out Lennon and Maisy's book In the Waves here.
