Following Chris Brown's shocking love child allegations, ex-girlfriend Karrueche Tran is now allegedly worried that she may have STDs.

According to HollywoodLife.com, the model found out her ex-boyfriend secretly had a 9-month-old daughter by reading reports online.

"Karrueche found out about the baby last night, along with the rest of the world, when she read the news online," a source revealed. "At first she thought it was a joke -- she couldn't believe what she was reading."

"Karrueche had no idea Chris had a baby with Nia," the source added. "He never brought it up nor tried to warn her."

After announcing her breakup with Breezy via Twitter, Tran is supposedly concerned about her health.

"Karrueche's day will be spent in the doctors office. She's rethinking everything Chris ever told her," another source alleged. "She's keeping her fingers crossed that she doesn't have any STDs. She was gone for a month working on a film and had sex with him before she left and when she came back. She's hoping she doesn't have to pay for it now."

"He should have had enough respect to tell Karrueche he was involved with other women," the source added. "Karrueche, at this point, wouldn't be surprised if he had other kids out there."

HollywoodLife.com also reported there is no chance of the longtime couple getting back together, as Tran can no longer deal with Chris Brown's infidelity.  

"Karrueche will never forget Chris Brown but... she's so over this dude. The relationship is over. She really can't do this with him anymore," an insider said.

"She's removing herself from Chris Brown entirely. She doesn't care about her clothes and all the other things at his house," the insider continued. "She never, ever wants to see him again or be in his presence. She's absolutely disgusted by him and his deceiving and manipulative ways."

"Karrueche didn't like him cheating but she dealt with it but this is something she never expected," the insider added.
