AceShowbiz - Antonio Brown and Keyshia Cole's relationship has seemingly hit a sour note after the two were hit with dating rumors. While the R&B artist has publicly expressed that she misses the former NFL star, he doesn't seem to reciprocate the feeling.

Over the weekend, Keyshia posted pictures of her and her "Don't Leave" collaborator on her Instagram Stories. She wrote, "Missing him a lot," and "Miss him! A lot," over the snaps.

Apparently catching wind of Keyshia's Stories, Antonio has re-shared a clip of a woman's back with a tattoo of his initials in the lower-left corner. He first posted the video in April and many speculated that it was Keyshia.

The athlete, who is now a free agent, also included their joint song "Don't Leave" in the background. However, he appeared to mock her in the caption as writing, " 'You Ain't Pimpin Until You Hit An RnB Diva' #FreeAgent #KeepPimpin."

Keyshia later responded to AB's post, hinting that he, for an unknown reason, was "mad" at her and she has apologized to him. "This the second time you posted this @AB but the captions changed don't be mad at me no more babe, I said I apologize," she begged to him.

Keyshia has also taken time to respond to fans who commented on her situation with Antonio. To a fan who is rooting for her, she wrote back, "Thank you! Lmao! It's all good. I'm used to it! Always so hard on me. No love lost."

Another user trolled her as writing, "AB put it down on @KeyshiaCole she never had a love like his before…. OBVIOUSLY." She clapped back, "OBVIOUSLY you KNO nothing. You're just assuming what u think u KNO." She added in a separate tweet, "And if u wanted to KNO, you could've taken your changes at asking."

Keyshia and Antonio first sparked dating rumors in March after they filmed a music video for his single "Don't Leave", which features the "Love" hitmaker. He fueled the speculation by sharing a video of someone believed to be the R&B diva sporting the "AB" tattoo on her left lower hip. They have never confirmed they're an item, though.
