Chris Brown did not take kindly to some of his fans who criticized his recent weight loss.

“The funniest [expletive] is the comments on me being too skinny! Half of y’all [expletive] are super obese and fat as [expletive]!” the newly signed Wilhelmina model told a follower on Instagram.

He then shared information about his fitness regime.

“I dance and workout constantly! It’s called being healthy. Some need stop running their mouth and get that fat [expletive] on a treadmill. I can hear u wheezing on my comments [sic].”

Meanwhile, Brown seems to miss his "former" flame Rihanna. On Wednesday, he instagrammed a photo of himself with Rihanna.

 “Always started with Breezy, the letter B,” was the photo caption, but Brown later deleted the picture.

It seems Rihanna and Brown are taking a break from each other, as Rihanna is taking a vacation in the Barbados with her best friend Melissa Forde.

“Being single sucks. The only thing I get to do is whatever the [expletive] I want to do,” read the caption on a postcard she tweeted earlier this week.

An insider told Perez Hilton that while on the set of "The Voice" to perform her hit "Diamonds,"  Rihanna "made sure her people told everyone on the crew that no one could talk about Chris whatsoever, because she didn’t want to hear his name!”

Last week, while on the Wendy Williams show, singer Christina Milian addressed the relationship status between Chris Brown and Karrueche Tran, with whom she is close friends.

When Williams asked Milian about the love triangle between Brown, Tran, and Rihanna, Milian replied “From what I’ve always known, she’s his girlfriend. That’s where it lies for me.”

“I see everything in the media, but I don’t really get into the detail of it. But I think everyone has their own lives and how they deal with things."
