Chris Brown has refuelled rumours he wants Rihanna back, after he retweeted a lyric from her new single 'We Found Love'.

The couple famously split in 2009 after it emerged the 'Yeah 3x' singer physically assaulted her at a pre-Grammy party.

When RiRi posted the lyric, "Sometimes it feels like we found love in the most hopeless place", Brown favourited and retweeted it.

What do you make of all this... is Chris being nostalgic, or does he want her back?

But that’s not all the ‘goss’ surrounding Chris Brown. It appears that he was targeted by a fake agent who setup and announced a concert date for the singer in Vancouver - according to Brown's rep.

In the cease and desist letter Chris' legal team fired off  they have accused a company called EJ Media Group of fraudulently presenting itself as a booking agent in order to organize a November 10 concert in Vancouver.

The concert was announced to the public today but Chris quickly tweeted that it was phony.

Brown's rep has stated that they were alerted to the fake show when the venue -- the Pacific Coliseum -- contacted them. Apparently, the venue already wired $25,000 to EJ Media Group to secure the gig.

The cease and desist letter demands, among other things, that EJ Media return the money.

However, EJ Media Group in New York City has contacted TMZ to say it is NOT involved in the Chris Brown concert fraud. A rep for the company points out the cease and desist letter was sent to a Broadway address - but they're located on Fifth Avenue, meaning they're not the ones messing with Chris.

The rep says they are trying to figure out if someone else is illegally using their company name.
