After being together for years, things may have gone south between Cassie Ventura and Sean Combs (aka Diddy).

Cassie posted a photo on Instagram that shows a baby sleeping with a content: "How I sleep knowing that I'm single and nobody cheating on me." The photo was captioned with: "yesssss," according to Rolling Out. Sources say that she deleted the photo a few moments later but the post is still visible on her Facebook timeline.

Also according to Lovebscott.com, Diddy was rumored to be cheating on her with a woman named Gina Huynh. Sources say that Diddy took the other woman and her friends to the All-Star game in New Orleans.

The cheating was rumored to be a recurring problem between the two. It was also with the same girl. They were able to sort things out when it first happened but Diddy reportedly rekindled his romance with Gina. Cassie cut him of and then went to Africa for the filming of "Honey 3."

According to sources, Cassie was not answering Diddy's phone calls and Diddy allegedly took Huynh to the BET Hip Hop Awards in October. He later on took her to his Revolt Music Conference in Miami later that month.

When Casey learned that Diddy took Huynh to the Conference in Miami, she decided to break up with the the hip-hop mogul.

Both Cassie or Diddy have not talked to the media about their rocky relationship. Cassie has not posted any pictures of her with being accompanied by Diddy.

Diddy on the other hand, posted a photo of Cassie in a two-piece swim wear, next to a bottle of Ciroc with a caption: "I'm on dat."
