Rihanna & Drake 'romance fresh,' in love? Learn how rapper keeps Chris Brown's ex 'smiling,' Karrueche Tran jealous?

Rihanna and Drake are happy and "in love."

The Nothing Was The Same rapper keeps his romance with RiRi "fresh," which is why the relationship is working out so well!

An alleged insider for HollywoodLife.com reveals:

"Every day there's something new. There's a new smile on her face because either Drake said something to her that blew her mind or he wrote her a little private note or he sent her a funny but loving text message."

How sweet! Wonder if Chris Brown spoiled the 26-year-old "Diamonds" songstress like that? The source continues:

"Everyday he's doing something different to keep the relationship fresh and keep Rihanna on her toes... The thing he does best, every single time, is he keeps her smiling. And that is the key to a woman's heart, making her feel happy."

It would be easy for the 27-year-old "Days in the East" crooner to shower RiRi with expensive gifts, but he's taking the more emotional route. And it seems to be working!
