The career of Ross Mathews has only climbed since the overly excitable TV personality became an intern-correspondent on "The Tonight Show With Jay Leno." The late-night gig translated to stints on "Chelsea Lately" and "Celebrity Fit Club," "The Insider" and other fashion-forward variety programs. Lately, however, Mathews, now 33, has taken his exuberance on the road as a one-man show, and will be promoting his new book, "Man Up! Tales of My Delusional Self-Confidence," 8 p.m. Tuesday at the Colony Theatre (1040 Lincoln Road, Miami Beach). $28.75. 305-674-1040 or Ticketmaster.com.
