After being caught kissing on a roller coaster, Ariana Grande and Big Sean aren't exactly hiding their relationship, even if they aren't admitting that they're dating. However, now that the rapper has purchased the "Problem" singer some matching jewelry, things look pretty serious between them!

"Big Sean and Ariana Grande have been spending a lot of time together over the past few months. He got her that necklace because he felt that it represents a special meaning between both of them," a source told E! Online.

It's such a romantic gift and, even better, she's obsessed with it!

"Ariana would always compliment him on his necklace and when he got it for her it was his special gift. She loved it!"

The singer showed off her necklace in a recent selfie on Instagram.

We think it's so sweet that they're showing their affection for each other in romantic ways, even if they aren't publicizing their relationship.

"Ariana just gets him and he gets her so it works. They are big supporters of each other and understand each other schedules. They both like to keep a low profile when it comes to their relationship."

That's so cute! It's nice to hear that they support each other, especially because Ariana reportedly broke up with Jai Brooks because he wasn't there for her when her grandfather died. Her rumored new guy is spending a lot more time with her.

Do you think Ariana and Big Sean's matching necklaces are cute? Was that a romantic present? Let us know in the comments!
