'Love & Hip Hop' Star K. Michelle -- I Stand By My Story ... Memphitz Beat Me

"Love & Hip Hop" star K. Michelle isn't scared of the defamation lawsuit filed by her ex Memphitz Wright -- telling TMZ, she stands behind her story 100% ... that the music producer beat her during their relationship.

K. Michelle tells us, "I¹ve always been told that the truth shall set you free. I stand behind my story 100%. I came on the 'Love & Hip Hop Atlanta' show mainly because I wanted to give a voice and bring light to a very serious issue."

"I am very grateful to VH1 and Monami Ent. for the opportunity to tell my story, and touch lives worldwide ... I look forward to having my day in court and finally having the truth of my story confirmed in a court of law."

She adds, "Hopefully others will not have to go through this and then have their stories challenged to this degree because people now want to try to salvage whatever reputation they may have had."

We're told K. has since lawyered up with attorney Matt Middleton and plans to fight Memphitz in court.

Memphitz has sued K. Michelle over comments she made on the "L&HH" premiere this season, when she referred to an unnamed record producer who "beat her ass" during their relationship ... a thinly-veiled reference to Memphitz.
