He may only be 18, but Nick Jonas knows how to treat a lady. The baby Jonas and his 26-year-old singer girlfriend Delta Goodrem were spotted sharing a romantic getaway in Los Cabos, Mexico recently. Ironically, Nick tweeted just yesterday that he's got big news he "can't wait to share" -- and many are speculating that he could be engaged.

While we admit that a beach vacation would be the perfect spot to propose, we can't help but feel like Jonas is just a smidge too young to take the leap, and we're not sure that the drones of young girls who fantasize about him are quite ready, either.

Still, it's been three months since the baby-face singer/producer told the ladies on 'The View,' "I think, the thing is, I’m in a really good place right now as far as my personal life goes. I usually keep the details of my relationship to myself." We took that to mean that things were getting serious for him, so it wouldn't be terribly far-fetched for things to have progressed to wedding bells since June.

Nick and Delta were seen enjoying one another's company at the Mexican resort while swimming, sunbathing and holding hands.
