The night before, Ri battled the rain while heading to Cuckoo Nightclub with her BFF Melissa Forde.

“I didn’t want to ask her to sing. Me and Evan [Goldberg] were like, should we ask her to sing? First, we didn’t even want to put her in the scene with Craig [Robinson] singing, like it’s too much – Rihanna singing – and we didn’t want to ask her to sing. So Craig thankfully sang at her and she sang back,” Seth Rogen shared about Ri on the set of This Is The End.

Seth added, “I’d never met her either. She was so nice. Very low key, low maintenance.” Check out the video below!
