A source told ET that the "Work" rapper and singer were spotted "kissing" and getting "very touchy feely" while at the club. "He really didn't leave her side until he performed," the source noticed. "They arrived together in the same car and left together around 5 a.m."
Drake was there to host the club's first Summer Sixteen after-party, and performed a few of his hits following his sold-out concert at the American Airlines Arena. While his attention was directed at Rihanna, a few other famous faces were at the venue, including Future, Lil' Wayne, Bow Wow, Flo Rida and DJ Irie.
The 29-year-old hip-hop artist appears pretty smitten with RiRi, with a source telling ET, "He is so into her."
"They are fully dating," the source says. "No one really knows how long they have been 'official' -- they just decided to let it become a thing instead of hiding it from everyone. They're happy."
