Blake McGrath -- the 23-year-old hottie from J. Lo's MTV reality show "Dancelife" -- went dangerously wild outside of Hyde last night.
Pimping season two of his show, the dancer screamed like a madman in his car on busy Sunset Blvd., then after quickly glancing at the street for oncoming traffic, jumped into the road and pulled off an effortless roundoff, back handspring back flip -- in the middle of the street!
McGrath's MySpace page reads, "I love to laugh and do random, stupid things." Yeah, that's about right.
