We can't verify the Rihanna rumors, but we can tell you this:
Chris Brown absolutely loves grabbing his crotch in concert.
The 23-year-old singer made an impromptu performance Tuesday night at Power105.1's DJ ProStyle Birthday Bash at the Hammerstein Ballroom in NYC.
Appearing shirtless and nearly dropping his pants faster than when he (supposedly) got Rihanna pregnant, he showed off his black Polo RL underwear.
Good thing this was NYC and not Louisiana, where a town recently passed the first-known too-saggy pants ban, making such style a violation of the law.
Brown also couldn't help tugging at his junk. Lovely.
"I love NYC," the R&B star tweeted Tuesday before the show. "The line Is around the block. Lets turn up tonight! #nodrama #staypositive #lovemylife."
Brown followed up post-performance by saying, "I love all my fans who came out tonight. Wasn't supposed to perform but I couldn't resist. I l0ve y'all!"
And his manhood, apparently.
