Big Sean sends Ariana Grande videos of him singing.

The 26-year-old rapper - who has been dating the 'Problem' hitmaker for several months - is reportedly creating little videos for the 21-year-old singer so she doesn't feel too upset when he works away.

A source shared: ''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.''

The 'Beware' hitmaker is believed to be ''putting in the time'' to ensure his relationship with Ariana is successful whilst the 'Break Free' singer is also working on being more ''mature'' for the sake of their relationship.

The source continued to HollywoodLife.com: ''Sean is extremely dedicated to his career so there are times that he can't be with her as much as she wants and that causes fights. But they're figuring it out, he puts in the time.

''And she's working on being mature about it. As much as she loves her work there is another part that would give it all up to just spend 24/7 with Sean, but he pushes her, he won't let her do that. He pushes her to do more and be more, he's good for Ariana.''
