The perfectly coiffed hair! The dreamy eyes! The heartfelt love songs! Boy bands are back -- and we can't get enough of them.

Since the beginning of 2013, two groups of guys have caught our eye: Emblem3 and Lawson. History has shown us that there is always room for two successful boy bands (ahem, 'N Sync and Backstreet Boys) but that doesn't mean we can't pit them against each other, right?

When they finally hit the big 2-1, Emblem3 will owe Simon Cowell a drink or two. The music mogul took the trio under his wing after they were booted from the 'X Factor,' and now they're opening for Selena Gomez! The boys -- Wesley, Drew and Keaton -- released their first single, 'Chloe (You're the One I Want)' and their debut album will drop on July 30.

Lawson, however, may have hits that date back to 2009 in the U.K., but are just now breaking into the States with a sound reminiscent of Maroon 5 or the Script.  And like the Wanted (who they have previously opened for), the boys -- Andy, Ryan, Joel and Adam -- are a quartet from England. They are also rubbing elbows with a famous singer -- B.o.B! Their latest single, 2013's 'Brokenhearted,' features a verse from the rapper.
