After Selena Gomez checked into a hospital with nausea and dizziness following 'The Tonight Show' last month, the web went wild with a whirlwind of rumors that she might be pregnant with Justin Bieber's baby. While we think that is probably (hopefully) not the case, the Biebs has been schooled on safe sex repeatedly to ensure accidents don't happen.

“Justin’s been told straight up that if he’s having sex, he had better use protection," an insider reports to Star magazine. "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."

It's true that Selena and Bieber have been spotted hand-in-hand all around the country together -- and even wrapped up in one another in Hawaii -- but we bet their mamas have taught them how to handle sticky situations.

Selena tried to nip speculation in the bud from the get-go by telling reporters that her hospital stay was a result of malnourishment and exhaustion. Still, Beliebers and Gome-ites can't help but wonder what happens between the couple behind closed doors.

Just before Selena entered the hospital on June 9, she and her beau were seen in Canada, visiting Justin's family. Since then, they've been seen and heard in public sharing some very audible 'I love you's,' which has some fans worried that they might be moving a bit too fast.

We think that at 17 and nearly 19-years-old, the young idols are old enough to make their own decisions. Still, that doesn't make the idea of a mini-Bieber any more comforting. Stay safe out there, kids!
