Wall, 22-year-old Washington Wizards point guard, has been communicating with Tran publicly on Twitter since last December. However, blog websites like mediatakeout.com took notice of the pair's most recent exchanges on the social media networking website.
"I believe in being strong when everything seems to be going wrong," Tran tweeted last week in a message that was reposted by Wall.
Although Tran and Wall have yet to officially confirm dating one another, Brown recently let it be known that he would be more comfortable with his ex-girlfriend dating an athlete instead of a singer.
"That would be a little close to home. At the end of the day, I think it should be a respect boundary," Brown said on New York City radio station Power 105.1 fm's "The Breakfast Club" recently. "Now if you go on to an athlete … that's different but don't s--- in my backyard."
Wall responded to a message from Brown on Twitter recently, which further fueled speculation from numerous blogs.
"Trust is a terrible thing to waste," Brown tweeted.
The NBA guard responded to the singer's general message.
"Real Talk," Wall added in agreement to Brown's message on the social networking website.
Tran has been open about getting over her relationship with Brown.
"I mean of course. Any breakup is hard regardless … stuck in the bed," Tran said earlier this year in Rolling Out Magazine. "I've had my moments but I put that all in the past."
The model and clothing designer said her ex-boyfriend knows that his actions were wrong.
"I mean he knows he's wrong. But things still happened the way it did," Tran said in Rolling Out. "That's on him, that's his actions not mine."
