To commemorate the big day, which took place on Sunday, the youngest member of the Jonas Brothers posted a sweet snap of the duo on Instagram. “I could stare into your eyes forever,” he captioned the post. “I love you baby. You are the most thoughtful, caring and wonderful person I have ever met. I am so grateful we found one another. Happy birthday beautiful.” In the photo, we see Priyanka (glowing in a yellow dress) sitting on her hubby’s lap while he lovingly gazes into her eyes.
