Look who made it rain together till the sun came up!

Rihanna and Drake met up at a Houston strip club in the wee hours Thursday and together dropped more than $17,000 before their outing was over well after 5 a.m., according to a dancer who entertained the "Take Care" duo.

While performing in Dallas, Drake showed up at Rihanna's rescheduled stop on her Diamonds World Tour, after which he reportedly took her out to dinner, and then RiRi returned the favor in Houston last night. She was spotted in the audience at Drake's show at the Toyota Center, dancing and singing along in the company of a pal and her assistant.

"Me, @KirkoBangz and my baby @rihanna turnt up at @Drake 's concert last night lol," tweeted Marcus Martinez, who snapped a pretty clear picture of the Barbadian beauty in the VIP section.

And later...she and Drake apparently decided it was time to let someone else do the dancing.
