Selena Gomez, Miley Cyrus, Demi Lovato and Taylor Swift are connected on more levels than one. The music, movies and television shows are just a few factors that connect these ladies. In a lot of instances, these Hollywood stars have been subject to the world of dating and cheating. Check out the most complicated connections in the business involving today's youngest and brightest stars.

Before Justin Bieber and Selena Gomez ever got together, Selena Gomez was involved with yet another singer. Of course, that singer too was involved with Selena's co-star from Disney. The connections pretty much get complicated from that point forward.

Like the famed "Jelena" duo, before "Haylor" had even been coined, Taylor Swift had quite a dating history. Swift had been connected and involved with a few celebs namely Taylor Lautner, Jake Gylenhaal, John Mayer, Ed Sheeran and a whole lot more.

Unlike Swift however, Miley Cyrus who had constantly been compared to the country crooner, had only two serious relationships. Still, Cyrus had her fair share of scandals involving one or two men outside of the industry.

Selena Gomez is also another starlet currently involved with a lot of dating rumours since her split from Justin Bieber. As of late, Selena Gomez had been spotted with co-star David Henrie from "Wizards of Waverly Place" to Austin Mahone.

As for Selena's BFF, Demi Lovato has lied low on the dating games but the "X-Factor" host had her share of the rumours early in 2013. Lovato was said to be dating One Direction's Irish member, Niall Horan. Ironically, Horan was also said to have briefly dated Selena Gomez soon after Selena split up from Justin Bieber.
