The guys of the Backstreet Boys have come a long way since their oversize suits and matching Matrix-esque looks, but they're still as close as ever. On Saturday, Kevin Richardson and AJ McLean made dreams come true when they reunited at the LA premiere of Rogue One: A Star Wars Story. Kevin brought along his 9-year-old son [1], Mason, and they all gathered on the red carpet for pictures. In addition to snapping photos, AJ shared a few shots from the event on Instagram, including one of him posing with Darth Vader [2], writing, "What up Vader? How's your mom???" While the Backstreet Boys have been busy performing at a series of Jingle Ball concerts throughout the past couple of weeks, they're also gearing up for their Las Vegas residency [3], which kicks off on March 1, 2017 at The Axis at Planet Hollywood Resort & Casino.
