Rihanna is currently vacationing in Barbados with her family at a $21.8 million mansion, but it looks like ex-beau Chris Brown is still on her mind, and she's clearly still on his!

Rihanna uploaded a picture of them holding hands to her Twitter account on Thursday, writing, "#THROWBACKtolastTHURSDAY," and he tweeted the above shot of the two from December 10, only to delete it 15 minutes later!

Almost two weeks ago Rihanna was seen with Chris in Paris and London after he allegedly ended his relationship with Karrueche Tran, and shortly after that RiRi posted a pic of the two together and wrote:

    "Damn....... I miss my n***a #thuglife #BFFlife." However, their reunion didn't last long, as Chris reportedly got back together with Karrueche just a few days later. At the time, RiRi tweeted, "Never underestimate a man's ability to make you feel guilty for his mistakes."

While we can't even keep track of how many times Karrueche and Rihanna have kissed and made up with Chris, just the other day Karrueche's pal Christina Millian seemingly confirmed that Rihanna was no longer in the picture when she told Wendy Williams, "You know what, from what I've always known, [Karrueche]'s his girlfriend ... I think they make a great couple."

Way to keep us guessing guys!
