Justin Bieber And Selena Gomez: Heating Up Too Fast?

Selena Gomez and Justin Bieber

These two are fully engaged in young love, but could it derail their careers and lives?

Justin Bieber and Selena Gomez have been on a huge red-carpet tour as a couple, their latest stop at the ESPY Awards earlier this week. They've also been spotted on vacation in Hawaii, with arms wrapped around one another in the waves and on the beach. It's easy to forget the pair is just 17 years old and 18 years old respectively.

Their support systems haven't forgotten, though. According to Star Magazine (via OK! Magazine), Justin has been warned about the consequences of this seemingly innocent young love.

"Justin's been told straight up that if he's having sex, he had better use protection," a source said. "He’s young and full of hormones, the last thing he and Selena need is to make a terrible and costly mistake.

"Everyone knows their intentions are good, but they also know how easy it is to get worked up when you’re young and in love. It would only take a few moments of weakness to cause what could be a lifetime of regret."

Last month, Selena was hospitalized after the couple's romantic getaway, apparently for dizziness and nausea, causing many to speculate that she was in the early stages of a pregnancy. Later, we found out she was simply malnourished, low on iron and totally exhausted from her career obligations. We hope she's feeling better... and that she slows down...

But still. It's hard not to worry about Justin and Selena's futures. These kids are so young, and so talented. We hope they're smart when it comes to their careers and their love lives.
