Rihanna and Chris Brown seem to be off-again after the 23-year-old singer unfollowed the beauty on Twitter.

The move came after a Rihanna fan, Justin Laboy, posted pictures of himself kissing Rihanna after one of her concert performances in Newark, N.J. The 25-year-old is on her “Diamonds” world tour, which began March 8 in New York City.

"Me and my wife @Rihanna out here tonight," Laboy said in a photo caption after posting a picture of himself kissing Rihanna’s cheek. She kissed him back on the cheek, and he made sure to post that picture on Twitter, too.

Laboy later tweeted: 'Me and @rihanna and you ain't even know it!'

In the photos, Rihanna is wearing a see-through “Oakland” shirt, a chunky gold necklace, and a backwards baseball cap. She looks quite happy with the fan, and it's unclear if they knew each other prior to that night.

Chris Brown was clearly not pleased when he saw the photos, tweeting afterward, “Just remember to keep ya [expletive] head up …[expletive] is overated now a days [sic].” He then proceeded to unfollow Rihanna and re-followed ex-girlfriend Karrueche Tran.

If Rihanna and Brown did in fact split, that would explain the rumored girls' trip that she and Katy Perry are taking to Africa. The two are reportedly friends again, after falling out over the Barbadian singer’s relationship with Brown.

The former best friends stopped hanging out for some time over Brown.

Perry wasn't pleased that Rihanna has gone back to Brown after he physically assaulted her in 2009, the New York Daily News reported.

"Katy fears Rihanna is making a huge mistake and doesn’t want to be part of it,” a source close to Katy told Confidenti@l, the newspaper’s gossip column, earlier this year.

But it seems that Perry doesn't have to worry about Brown for the time being.
