Ariana Grande has been touring in Europe promoting her album "My Everything" for some time now, and her alleged boyfriend, hip-hop artist Big Sean, seems to have missed her.

Now with the pop singer finally back in LA, the rumored couple is finally reunited. In fact, Big Sean took the homecoming to social media. The rapper tweeted, "Lil kitty in the building."

Fans are assuming that the "lil kitty" Big Sean was referring to in the tweet is Grande, who's been sporting cute cat ears for a while now.

The 26-year old artist has a show at the SupperClub in Los Angeles on Oct. 23. and according to a report from HollywoodLife, Grande was rushing to get back to LA to meet with her boyfriend and to see him perform.

"Ariana is telling people she has to be back in time to see her boyfriend perform," a source told HollywoodLife. "She wants to make sure she's there to support Big Sean. Ariana might even get up on stage with him. She's having fun in Europe, but she's homesick."

The couple wasn't particularly public about their relationship, except on social media. HollywoodLife reports that just last week, the 21-year old singer posted a sexy photo from her bed on Instagram, tweeting it, "Wasn't sure what to caption this so I asked my mom and she said suck my ass."

Big Sean especially noticed the photo, leaving a comment that says, "I miss that view. Get back here."

Grande has confirmed that she's exclusively dating Sean Anderson, aka Big Sean, in an interview with Telegraph. When asked about the status of their relationship, she replied, "Yes. He is one of the most amazing men in the whole world, and that includes my grandfather and my brother. I think the world of him, and he's an amazing person. That's kind of all there is to it."

According to the Telegraph article, rumors about the two started surfacing when Big Sean contributed to Grande's second album "My Everything."

E! Online reports that during Big Sean's appearance on "On Air with Ryan Seacrest," the rapper said that Grande is very special to him, and that the chemistry between the both of them when they work together is great.

"That Ariana is very, very special. She's very special to me," he said. "Everything she has going on is good with her, everything I have going on is good with me, everything between me and her is good, and I'm just going to leave it at that," added Big Sean.
