Where to see star impersonators -- Britney Spears, Janet Jackson and Elvis are some of the faux-perfomers on stage in Vegas

LEGENDS IN CONCERT, Imperial Palace (starts at $39.95 per ticket) A Vegas staple for more than 20 years, this revue currently features Janet Jackson, Gloria Estefan, and more rock relics than a VHI special.

AMERICAN SUPERSTARS, Stratosphere Casino Hotel and Tower ($38.75 per ticket) A virtual cornucopia of celebrity impersonators, including Michael Jackson, Elvis, and Britney Spears. Expect lots of bad wigs.

LA CAGE, Riviera Hotel & Casino (starts at $55 per ticket) Highlighting female impersonators, La Cage is headlined by Frank Marino as Joan Rivers. In real life, Marino actually resembles an ’80s Richard Marx.

BARBRA & FRANK: THE CONCERT THAT NEVER WAS, Riviera Hotel & Casino (starts at $39.95 per ticket) For those of you who yearned for a Streisand-Sinatra matchup. Anyone?

ALL SHOOK UP: THE ULTIMATE TRIBUTE, Elvis-A-Rama Museum ($17.95 per ticket) Watch the ”No. 2 Rated ’70s Elvis,” Johnny Edwards, reenact Presley’s greatest hits. They couldn’t book the ”No. 1 Rated ’70s Elvis” because he’s, um, dead.
