'Amazing Race' Star's Bum Rap After Losing Million Dollar Prize


"Amazing Race" cast-off Vanessa Macias isn't letting a little thing like blowing a million dollar competition get her down, instead she's cultivating her next career move ... as a Sir Mix-a-Lot wannabe.

Macias -- known as one half of "Dating Divorcees" -- made it all the way to the final four of the reality TV show ... and was just shy of winning the million-dollar prize before getting axed on last Sunday's season finale.

Instead of jumping head first into a pint of rocky road while the episode aired ... the Texas native took the opportunity to show off her stellar rapping skills at a bar in San Antonio called Boneheadz  (yes, that's actually the spelling). 

In the video -- which is pretty great -- you see Macias bring a whole new flavor to Sir Mix-a-Lot's classic "Baby Got Back" ... a flavor the world might not have tasted, if not for her tragic elimination.

Cheers Vanessa ... you may be poor -- and bad at rapping -- but you sure do got back.
