Some of the biggest names that dominated the countdowns on TRL [1] back in the day are making your childhood dreams come true by reuniting for a nostalgia-filled tour. Dream, Ryan Cabrera, O-Town, and 98 Degrees all stepped out on Tuesday at the launch of their tour, My2K, at Faculty in LA. The tour, which 98 Degrees will headline [2], kicks off July 8 in Kansas and wraps on Aug. 28 in California. While we're sure the bands and Ryan will bust out hits like "Liquid Dreams," "He Loves U Not," and "True," we also hope they can bring back some late-'90s and early-2000s staples, like butterfly hair clips [3] and all-denim outfits [4]. Keep reading to see more of their red carpet appearances, and then check out the ultimate '90s slow song playlist [5].
