It's no secret Big Sean and Ariana Grande are two of the biggest musicians in the nation, so it's no wonder they have to find creative ways to keep the fun and spice in their relationship as they travel around the globe for separate projects and spend lots of time apart.

An insider told Hollywood Life Wednesday that they have no problem in keeping their love strong.

"When he's away, he checks in with her all the time, which really helps. 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."

Still, their celebrity status doesn't keep them from having issues like an every day couple.

A second source told the entertainment news site that they both have "get jealous" every once in awhile. But it's not to the point that would threaten their relationship.

While the couple usually stays quiet about their relationship, Big Sean recently dished on dating the fellow superstar with Power 105.1's The Breakfast Club.

He said they started as friends but began dating months after. Even though they never came out together as a couple, they could spent weeks playing coy about rumors until a snapshot of them locking lips on a roller coaster surfaced online and went viral.

But Big Sean said he wasn't thinking about fans possibly catching them together when the picture was taken. He was just spending time with his girlfriend. Check it out at the 6:30 mark in the video below.
