Nick Jonas is such a jet-setter! Earlier in the weekend he was spotted greeting girlfriend Delta Goodrem, 26, with a hug at LAX, and Sunday he headed back to the airport.

Nick drove his snazzy classic car Sunday afternoon, then headed to LAX en route to Chicago. In Chi-town, he had fun practicing with the Cubs, but he's there for business -- not just pleasure. The 18-year-old musician is judging the Quaker Chewy Superstar Search.

Nick is growing up into such a sexy guy! We can see what Delta sees in him!
