Supportive as Ever: Justin Bieber Joins Selena Gomez on World Tour

Selena Gomez might be taking a break from the music scene but she most definitely isn't taking a break from her world tour.

Yet, what's this about Justin Bieber joining her? Bieber proves he's not only sweet but one very supportive boyfriend by being right behind his "Mamacita Gomez" - literally.

They've been on the news countless times for numerous dates and a lot of photographed PDA moments. Though people would think they're probably already tired of each other after dating for a year, these two prove their still very much in love and they aren't ashamed to show it.

They've spent New Year's Eve together and spent a few dates together after. Proving that they act their age, these two spent a late night date at Disneyland where Justin used his slick, smooth moves to give his girlfriend a little bit of loving.

So what's up with the two now? 'Seliebers' will be hyped to hear that Selena Gomez is up and ready to continue her world tour and who's she got right behind her cheering her all the way? It would be none other than her boyfriend, Justin Bieber.

Justin posted another picture to his Instagram account dated January 22 with the caption "airport sleep". The 17-year old singer was out cold, napping on the seats at the airport.

It's no surprise if the date was a coincidence with Selena Gomez's' Puerto Rican concert, where she too was spotted at the airport hugging a pillow and looking equally sleepy herself. So if fans simply put the puzzle pieces together, Justin was along for the concert ride.

Well, it isn't the first time he's done that.

In fact, just a few days ago, Justin showed up at Selena Gomez's' acoustic UNICEF show last January 20 at the House of Blues in Sunset Boulevard of West Hollywood. He proves he isn't only great at belting out songs and moving it on the dance floor but this singer knows exactly how to be one sweet and supportive boyfriend.

Despite a few Hollywood couples going through celebrity splitsville, these two aren't fazed one bit. Maybe Johnny Depp, Russell Brand and Seal could learn a thing or two from the Bieber on how to treat your lady right.
