In case you didn’t get the memo, there's nothing mellow about Rihanna slaying in yellow!

Last night in London, the 31-year-old "Wild Thoughts" singer was spotted partying it up in a stunning jewel-toned, yellow, off-the-shoulder satin dress with a mini suede tote by Medea, a pair of sunglasses from her Fenty collection and matching canary-colored heels that effortlessly had her glowing like Fenty Beauty's “Killawatt” highlighter.

Speaking of Fenty Beauty, it turns out RiRi was actually celebrating the launch of her new "Sun Stalkr" bronzer with an invite-only event held for influencers. 

Going off the series of social media posts, we’d say the event went without a hitch as some of your favorite Instagram influencers enjoyed a night of trying new products, posing for photos with Rih, playing beer pong and even singing karaoke!

See some of the moments that made the party lit below:

We're so jealous! How did our invite get lost in the mail? *facepalm*
