Issa Rae was beaming during Usher s performance Saturday in Las Vegas, and while the Insecure actor is certainly a fan, that glow was the result of being serenaded in front of thousands as Usher brought her onstage for an intimate rendition of Superstar.

Issa, do you mind if I just sing a couple songs to you? Usher asked her at the Dolby Live venue at the Park MGM . Can I just serenade you a little bit?

Usher, who began his residency at the resort and casino in July, posted the tantalizing footage Monday on Instagram. It showed him singing for the Emmy-nominated actor while gazing into her eyes before taking Rae onstage by the hand to sit with him on the steps.

Come on, were just gonna flip the whole show up, he told Rae. I want you to just sit right here with me.
