Drake 'creeping' with Rihanna's sister Samantha Fenty!? [PHOTOS]: Rapper makes RiRi jealous with flirtatious ways?

It's pretty obvious that there's an instant connection between Rihanna and Drake - but the popular "Take Care" duo have yet to make their "relationship" official. Therefore, Drizzy has every right to flirt with other girls - including RiRi's own sister, Samantha Fenty!

The Nothing Was the Same rapper and Miss Fenty were spotted "getting cozy" at Puro Sky Lounge in Germany on Thursday evening (Feb. 27). The infamous gossip webloid MediaTakeOut.com has the exclusive photos here.

Drizzy had just performed at Berlin's O2 World Concert. Meanwhile, RiRi was busy enjoying Paris Fashion Week a few countries away.

But there's also a chance he's trying to make the "Diamonds" songstress jealous, so that she'll settle down and make their relationship exclusive...

What do Mstars fans think?

Earlier this week, RiRi and Drake got hot-and-steamy onstage during a performance in Paris, prompting even more dating rumors:

Who knows what might happen!
