The woman, who goes by the name of Lil Marche on Twitter made the announcement is dating by sharing intimate pictures of them together online including ones in their underwear, kissing and cuddling.

"Can we change the stigma of incest?" she wrote online. "I shouldn't be limited to who I love because we're related.

"I'm just happy and in love, just so happen to be my cousin. What's the deal? Y'all need to get over who I f***. Cousin or not."

The post attracted a number of reaction from Twitter users with most people criticizing their relationship.

"I don't care what anyone says," she responded to the negative messages.

"Y'all not going to shame me - I'm in love. No need to be ashamed of it".
