They may be approaching their two-year anniversary this December, but Kevin and Danielle Jonas are still in the puppy-love phase.
Kevin shared a photo of the pair cuddling their Morkie, Riley, on Sunday with a simple Tweet
Riley became part of the Jonas family just after Kevin and Danielle's honeymoon in Mexico. "She usually sleeps with us, between our two heads," Kevin told PEOPLE
last year. The trio has stayed inseparable ever since.
The too-cute Twitter photo, in which Kevin is kissing his wife's forehead, really resonated with their fans, including one who Tweeted: "You two are adorable. Love you both! Hope to one day find love as true as yours."
