The Bajan pop star uploaded a candid snap of herself wearing no make-up in the early hours of Tuesday morning (17 September) and appeared a little blurry eyed and fatigued.
It also looked as though she had just woken up (or maybe not even slept yet!), since her quirky new mullet hair 'do hadn't been styled.
Rihanna intriguingly captioned the picture: "What now?"
Does this mean that she's feeling slightly frustrated with her jet-setting lifestyle? Or is this simply her way of asking her followers what she should eat for breakfast? Who knows!
RiRi then took to Twitter to share a few telling lyrics from rapper and ex boyfriend Drake's new album, which leaked online this week.
One of her tweets (taken from the song 'Wu-Tang Forever') read: "It's yours...nobody else's".
She also tweeted: "Don't think about it too much, too much, too much, too muuuch!", which is taken from Drake's track titled 'Too Much'.
Although thousands of fans (and celebs alike) were showing their support and love for the rap star's new album yesterday, it is interesting to see RiRi openly quoting lines from some of the popular songs.
Her public appreciation for Drake's music may be a stab at ex-boyfriend Chris Brown, who is known to have an ongoing feud with Drake and has made it clear that he and the Canadian rapper will never be friends.
It is thought that the artists initially fell out when news of RiRi's previous relationship with Drake surfaced and they soon came to blows in a New York nightclub, which resulted in a bottle-throwing brawl and a lawsuit (although this was dismissed in July).
Could Rihanna be trying to provoke a reaction out of Chris with these tweets? Could she be getting close to Drake again? Or does she just really like the album?
We have so many questions!
