Singer Ariana Grande and rapper Big Sean were caught kissing, based on a blurry photo at a club, though neither party has yet to confirm a relationship, according to J-14.

The picture was taken at an iHeartRadio party in Las Vegas, Mstars News reported.

Neither celebrity has confirmed to media that they are in a relationship but sources have confirmed they went on a date, and mysterious pictures and tweets on Ariana Grande's Instagram account suggest they are.

Both have fueled the rumor fire with admitting they are close and know each other and love each other's work, but nothing on the relationship.

MTV reported a recent photo on the Instagram account showing Grande as well as a shadowy male figure with Sean's signature backwards-facing baseball cap.

She tweeted on Sunday, "my baby loves me," according to J-14.

The two have worked together on two songs, "Best Mistake" and "Right There," and Big Sean said there was more to come.

He recently told MTV, "Me and her make a lot of music together and the chemistry between me and her when we work [it] is great."

In addition, he touts himself as being the first person to ever tweet about her music, and that the two of them have known each other from before her musical career taking off.

Grande started off as a character on a Nickelodeon show and has recently made it into the musical world.

Her top songs have been "Problem," featuring Iggy Azalea (which peaked at No. 2); "Break Free," featuring Zedd (No. 4); and with Jessie J and Nicki Minaj, "Bang Bang" (No. 6), according to Billboard.

Both her albums to-date have topped the charts in the first week of their release.

Their relationship continues to baffle media, who are eagerly trying to confirm the couple's commitment, but both parties have been able to tip-toe around questions every time they have been asked.

So far only video footage of them holding hands backstage at the Video Music Awards, as well as the recent photo at a party, are the only hard evidence of the relationship.
