Former Brit Backup Can't Stick It

TMZ's favorite sidewalk dancer, Blake McGrath, was out again last night , one-upping his sidewalk pirouettes from the last night -- by flipping out all over Hollywood and falling flat on his ass!


Cameras caught the "Dancelife" and "So You Think You Can Dance" star at both the Us Weekly party and Hyde, showing off his tumbling skills and pulling off some sick tricks with at least one less-than-stellar landing.

When he was done showing off, the onetime Britney backup dancer felt it was time to stick up for Brit's atrocious VMA performance -- calling it "amazing" -- and ironically calling Chris Crocker "f**kin' crazy."
