This past weekend-
A concert featuring three former teen idol singers from the 2000s — Ryan Cabrera, Aaron Carter and Greg Raposo — would be interesting enough. But the Boys of Summer show has added the group 5-L, made up of Booboo Stewart and his sister, Fivel (pronounced "5-L").
Stewart is an actor with many credits, but none as high profile as werewolf Seth Clearwater in the "Twilight" films. He is featured prominently in the final movie, to be released in November.
Of course, the others are no slouches. Cabrera was a top teen heartthrob in 2004, with Top 10 pop hits "On the Way Down" and "True." Carter was the dominant idol a decade ago as 13-year-old singer of "That's How I Beat Shaq." And Raposo was in the boy band Dream Street.
