Ariana Grande may be collaborating with rapper Big Sean in more ways than one. The singer released a new single, “Best Mistake,” on Monday August 12 that prominently features the rapper, available on EW.com, and now rumors are heating up that the pair is dating.

According to E! News, Grande and Big Sean were spotted at a movie theatre in Los Angeles. A source reports seeing them slip in relatively unnoticed and then kiss during a late night showing of The Purge. Glamour magazine spoke with Grande on Tuesday morning, and asked her if she was dating the rapper. The magazine reasons that her response—repeating the question “are you dating Big Sean?” to the interviewer—is not exactly a denial.

Both stars have been in the news for their most recent other romantic attachments. As E! News has reported, Grande broke up with her Australian boyfriend Jai Brooks last month shortly after her grandfather passed away. According to the source, “Ariana just felt he wasn’t there [for her] like he should have been.” Big Sean made headlines in April after calling off his engagement to Glee star Naya Rivera. His rep told E! that it was a “difficult decision” to call off the wedding.

Grande’s new album, My Everything, will feature Big Sean on several tracks, and arrives on August 25.
