Delta Goodrem and Nick Jonas recently escaped to Los Cabos, Mexico for some holiday time together. The couple’s romance is still going strong, with the two showing lots of PDA while sunbathing, swimming, and hand-in-hand strolling at a resort. In the early stages of their relationship, which reportedly started in May, they also travelled to Bali for a songwriting workshop, though this time ’round it seems like it was more rest and relaxation than work. Delta and Nick’s loved-up state has apparently spread to their friends, with Nick’s brother Joe Jonas spotted on dates with Delta’s friend Renee Bargh. Nick also teased his Twitter fans with this tweet: “I'm getting so excited about sharing my big news with all of you! Who thinks they know what it is?” Any guesses?
