Lady Sovereign is the Queen of Beers

Move over Lindsay Lohan, there's a new underage drinker in da house!

Pint-sized British rapper, Lady Sovereign, aka Louise Amanda Harman, needs to brush up on the drinking laws on this side of the pond.

While onstage Tuesday at Miami's Studio A, the 20-year-old singer belted out her hit song, "Love Me or Hate Me" while swigging a Corona.

Who needs a fake I.D. when you're famous?!
