Okay, Rihanna and Chris Brown are officially the most confusing couple ever.

Although the duo reportedly ignored each other while partying at the same club last Friday night, things seem to be going just fine for the on-again couple, who spent Rihanna's birthday yesterday frolicking the beach in Hawaii while smoking a blunt (or two). RiRi left little to the imagination, covering up her barely-there pink bikini bottoms with only a thin mesh skirt.

"#epic day already, I woke up to sunshine in paradise and #STAY done jumped 54 spots to #3 on the BillboardHot100!!," Rihanna tweeted, adding, "Walked up into #2013 like I owned a ho."

Although the "Stay" songstress has received a ton of criticism for taking Chris back, even from one of her BFFs, she has made it clear that she is happy and doesn't care how the public feels about her relationship. Well, to each their own...

How long do you think Chris and Rihanna will last?
