Joe Jonas might be ready to make his romance with Tatiana Gabriela social media official. "Enjoying my pinecone," Jonas, 36, wrote via Instagram on Friday, January 16, alongside a carousel of 10 photos featuring the boy band singer eating at restaurants and making music. In one of the photos, Jonas seemingly uploaded a pic of one of his black studded loafers next to an unidentified woman's leg. The mystery woman wore a pair of black, lace-up heels with fitted trousers.
