Chris Brown's ex-girlfriend, Karrueche Tran, recently took to Twitter to subtly deny rumors that she plans to get back together with Chris Brown.

Tran's tweet follows Brown's loving Instagram message to Tran on his birthday.

In an Instagram post that has since been deleted, Brown wrote, "Thx for making my bday a special. All my friends family etc.. #taurus season.. I have three special ladies celebrating this month. Mother's Day for momma. May 17th miss you know who."

Urban Islandz notes that Tran's birthday is on May 17, and Brown's message was mostly like in reference to her.

But despite Brown's attempt at mending his relationship with Tran, she is still adamant about remaining apart.

An Urban Islandz source says, "Karrueche wasn't surprised about the rumors because she is used to that BS in the media daily but when Chris tried to played it off like they are back together she had to say something."

The source added, "There are no chance of reconciliation at the moment, Karrueche still loves Chris but she recognized that he has caused her a lot of pain and has decided to step out of that situation. She wish him well."

So far, Brown has yet to respond to Tran's public denial of their relationship. However, HollywoodLife claims that Brown is still trying to win Tran back and plans to perform one of his love songs for her on her birthday next week.

"For Karrueche's birthday, Chris wants to sing 'Yo (Excuse Me Miss)' to her. That song reminds him of when he first met her, when he glanced over at her and knew she was the one," said the HollywoodLife source.

Tran officially broke up with Brown after discovering he had cheated on her and fathered a baby with video model Nia Guzman-Amey.
