Not only is Chris Brown expressing how much he loves his girlfriend Rihanna, he's also telling everyone that he owns her private parts.

In a video released by TMZ, Brown publicly claimed his ownership to "Nobody's Business" singer Thursday at a party at Emerson Theater in Hollywood. Brown randomly grabbed the microphone from the DJ and talked to the crowd about how a man should talk to his woman. "Every guy in this building has said one thing to their female. If you're not an insecure [person], and you let her have fun with her friends, I applaud you. But you gotta say that one thing to her, and I made this s**t up," Brown said.

Sources said that in a mixture of a rant and an impromptu song dedicated to Rihanna, Brown said "Don't make me have to tell you again that that's my p**** baby. It is mine, baby, babe, mine. Don't make me have to tell you again that that's my p**** baby. It's mine girl, it's mine girl, it's mine, so you better not give it away."

The singer also ranted about his dislike for rapper/rival Drake.

According to Vibe.com, moments before the DJ played 2 Chainz's Birthday Song, Brown went on a freestyle talking about his friends and about him readjusting to his different life in California. He ended the rap with a random "F--- Drake."

Despite the fact that Drake collaborated on Brown's Deuces Remix featuring also T.I, Kanye West and Fabolous, both rappers have a rumored beef that included an altercation at a New York club W.I.P last summer. Rihanna reportedly dated Drake after a relationship with Brown ended in 2009. Rihanna also features on Drake's song Take Care.

Rihanna is currently working on her Diamonds World Tour. She kicked the concert off in Buffalo, New York on March 8, where she was spotted wearing revealing costumes.

"We are really happy" Brown said at Elton John Aids Foundation Bash on Feb. 24. "We are back together. She is the most beautiful girl in the world."
