'Love & Hip Hop' Star K. Michelle -- $52,000 Bitch Slap

"Love & Hip Hop" star K. Michelle is finally getting a taste of her own medicine -- at least in the slapping department -- because the IRS just hit her hard.

Uncle Sam has filed a $52,415.09 tax lien against K. -- who famously slapped her co-star MiMi Faust this year -- claiming she didn't muster up enough tax dough in the years 2008 ($47,710.46) and 2009 ($4,704.63).

2008 was a big year for K. -- her singing career took off when she signed with Jive records. In 2009, she released a single with Missy Elliott. Things slowed down afterward, until she signed on for "Love" in 2012.

As the saying goes ... mo' money, mo' problems.
