Scantily clad: Justin Bieber and girlfriend Selena Gomez share a passionate kiss on the beach in Mexico yesterday where they are celebrating their year-long anniversary

They are two of the busiest teenagers in the world, but Justin Bieber and Selena Gomez make sure to find the time for their blossoming relationship.

Bieber, 17, whisked Gomez, 19, to Mexico for her friend's wedding, and the pair managed to get some much-needed r and r in between scheduled commitments.

The most sought after couple in young Hollywood appeared happy and relaxed as they sunbathed by the Cabo beach on their first anniversary together.

Bieber was snap-happy, taking pictures of his stunning girlfriend who was clad in an aqua-colored bikini. Later, the duo took a dip in the ocean and had fun on a pair of jet skis. After all their activity, they sipped on smoothies to cool down.

The two young superstars weren't hesitant to show affection in public, sharing a kiss by the shore.

With all their PDA, it's no wonder the public is assuming they're ready to tie the knot.

After Gomez was snapped leaving the airport with a diamond ring on her engagement ring finger, word spread like wildfire that the teen king and queen are set to say their vows.

Both Bieber and Gomez's camps denied the rumors of wedding bells in the near future.

"There is no ring and no engagement," a spokesperson for Bieber tells E! News.

Gomez's representative echoed the sentiment to Us Weekly.

"She is not engaged," the rep says.

It's safe to say that the pair isn't engaged for now, but if Bieber has anything to say about the matter, the fans of the pair might not have to wait for very long.

In an exclusive interview on September, the pop sensation admits that while he's not about to get married now, he wants to earlier than most people would expect.

"Well, by 25 or 26, I want to see myself, like, married or start looking for a family. I want to be a young dad," Bieber reveals to Women's Wear Daily.

"I want to be able to have done what I wanted to do - to be successful, to do a movie or whatever. But if the time is right, I definitely want to be married by 25," he adds.
