Drake 'Flirts' with WNBA Star Skylar Diggins AND Nicki Minaj on Instagram, Rihanna Jealous? [PHOTOS] Boyfriend Daniel Smith Fires Back

Rapper Drake's a huge flirt - although he's currently dating one of the hottest chicks in Hollywood (Rihanna).

Anyway, Drizzy gave a "shout-out" to WNBA baller Skylar Diggins on Instagram earlier this weekend, with no rhyme or reason as to why...

champagnepapi: "SkylarSZN @obobrien."

Sort of odd...

About a week ago he also shared this:

champagnepapi: "Amen."

Later on, he posted this snapshots of fellow YMCMB superstar Nicki Minaj:

Again, pretty random, considering rumors already suggest that the two hip-hop stars are secretly "hooking up." Apparently, Drizzy has a major "crush" on the "Pills N Potions" diva.

So, what's up with all the Instagram flirting? Drizzy might get himself into some trouble soon.

The 23-year-old Tulsa Shock athlete's boyfriend fired back at the Nothing Was The Same crooner with:

daniel87smith: "@Champagnepapi."

Back off, Drake, Diggins is already taken! Stick with RiRi, already!
