Mary J. Blige — Broke Bikini Babe!

0408_mary_j_blige_INFMary J. Blige isn”t letting a little thing like financial ruin stop her from vacationing in the Caribbean.

Rockin” a sexy green bikini, the 42-year-old cash-strapped R&B diva tried to get her mind off the $900K tax lien she got hit with in February … and defaulting on a $2 million bank loan last year … and the $250K bank loan her charity was sued for … by somehow finding the means to jet down to Puerto not-so Rico this weekend. 

All that drama has Mary feeling the heat.
