Ariana Grande and Big Sean are both big time music stars, so it must be tricky to keep the romance alive, right?

Well it would seem these two have no problem sticking together, as source tells Hollywood Life that Sean does everything he can to make it easier for him and Ari.

“A few days ago, he made a little video of him singing to her in an elevator. She loves that kind of thing. She just wants to know that even when they aren’t together he’s thinking of her.”

Cute!

Though their relationship isn't totally drama free, as the source adds: “Ariana and Sean both getjealous sometimes.”
