Drake treats Rihanna 'like a queen,' Chris Brown's ex officially inrelationship with Drizzy?

Drake and Rihanna have been partying a lot together lately, but are they finally ready to take things to the next romantic level?

Apparently Drizzy treats RiRi "like a queen," and the "Diamonds" songstress isn't used to being so spoiled with affection!

"He's a gentleman and you know Rihanna isn't quite used to all that," an insider reveals to HollywoodLife.com. "She's used to bad boys, the ones who are hood and swagged out and real ghetto like her ex. But even though she's use to all that ratchetness, it's a real treat when she's with Drake because everything flows well." 

Would dating the Nothing Was the Same rapper be a step-up from her previous relationship with Chris Brown? According to RiRi's close friend - yes. Drake and Rihanna "don't argue," and they get along very well. Drizzy knows when to allow RiRi to take over the spotlight:

"Drake's not all up in the club trying to be the star and get all the attention. He's real chill and laid back and that in itself turns her on... Drake's got swag of his own and he knows how to really treat her... It's going to be hard for her to date someone in the future other than Drake because she says, 'Since he's been treating me like a queen, I can't go back to bullsh*t.'"

The source also reveals, "She's already in a relationship with him - it's a friendship and it's a real close one."

Wonder when (or if) they'll make it official?
