Chris Brown has taken a page out of Rihanna's book and posted a saucy picture to Twitter.

Brown and his new GF Karrueche Tran posted the above kissing pic to Twitter with the caption: "head over heels."

We can clearly see that from the hipster face sucking picture dudes... Classy.

For those of you like us, who have hardly a clue who this Karruche chick is, this is all we could gather from her personal bio on her website.

1. She takes pictures of her food for her Tumblr page

And

2. She is a "self professed model."

Well, we guess we wish this young couple all the best.
