Karrueche Tran showed Chris Brown what he's missing by posting bikini pics while vacationing in Cancun with Lil Wayne's rumored girlfriend Christina Milian.

Meanwhile, the rumors about Chris Brown getting desperate to get the attention of his ex-girlfriend might be warranted when the "X" singer commented on a provocative Instagram photo of Karrueche Tran.

In the Instagram photo,  model Karrueche Tran can be seen teasingly licking her upper lip while showing her bikini booty to the camera. She captioned the image, "I'm president of the Itty Bitty Committee #ThirstyTuesday."

In one of the comments, Chris Brown wrote, "Thirst trap 101. Continue to be a lady beautiful...U are perfect...Don't let the Thot form from anger."

Thot is a derogatory term reserved for women. It means, "That hoe over there."

E! News claimed that Karrueche Tran and the "X" singer actually stopped talking prior to her finding out about Chris Brown's baby mama drama.

The article also claimed that Chris Brown "would reach out all day, every day, but Tran didn't want to hear anything from him and had refused to answer his calls."

Photos of Karrueche Tran enjoying the sun and beach in Cancun, Mexico with Lil Wayne's rumored girlfriend Christina Milian were published on Daily Mail.

"The exotic beauty - who dumped Chris after learning he had fathered a baby with another woman during their time together - retreated to the Mexican hot spot a few days ago," it said.

It was also an opportunity for Karrueche Tran and Christina Milian to showcase an array of different bikinis. From the asymmetrical stripes, leopard prints to camouflage bikinis that she wore, Chris Brown ex-girlfriend's svelte figure was really accentuated.

Karrueche Tran broke up with the singer when the Chris Brown baby mama drama was splashed all over the Internet.

In a Twitter post, Karrueche Tran wrote, "Listen. One can only take so much. The best of luck to Chris and his family. No baby drama for me."
