Just a few weeks after confirming her relationship with Big Sean to The Telegraph, Ariana Grande is now unveiling her love for her new beau via Instagram.

On Sunday, the "Love Me Harder" singer posted her first selfie photo with Big Sean, and the rapper reposted the photo on his own Instagram account and referred to Grande as "my baby."

The Daily Mail reports that the photo was taken while Big Sean and Grande were on their way to the "celebration of life" ceremony for Grande's grandfather, who passed away in July. Prior to her grandfather's passing, Grande reportedly canceled all of her performances and commitments and rushed to be by her grandfather's side on July 4. Grande's grandfather later died on July 22.

Although Big Sean and Grande's relationship is still fairly new, the two are reportedly getting very serious. Radar Online reports that Big Sean is very integrated in Grande's famil,y and the two are planning to spend their first holiday as a couple together.

"Her mother really likes him," a source said. "They would not be together without that approval, as Ariana is very careful who she lets into her heart."

The tabloid site also reports that Grande considers Big Sean to be her "soul partner."

Last month, Grande professed her love for Big Sean to the Telegraph.

"He is one of the most amazing men in the whole world, and that includes my grandfather and my brother," Grande said at the time. "I think the world of him, and he's an amazing person. That's kind of all there is to it."

In addition to her growing romance, Grande's music and acting career continues to rise. According to HollywoodLife.com, Grande is now being offered movie roles that she plans to "take advantage of" because her music career is "so hot." There is no news yet on which movie roles have been offered to Grande.
