What happens when two Hollywood It girls meet up at a fashion show? Besties at first sight!

Oscar winning Lupita Nyong'o and Barbadian singer Rihanna spent time together during the Miu Miu show during Paris Fashion Week Womenswear Fall/Winter 2014-2015 in Paris on March 5. The celebrity duo seemed to really hit it off before and during the show. In other words, there were selfies involved.

"#MiuMiu selfie with the sensational Rihanna @badgalriri. #Paris," Lupita wrote on Instagram, along with an amazing photo of her and RiRi.

The lovefest didn't stop there. The two stars sat in the front row together, schmoozing, posing for photos, and giggling. As for which other celebs joined them? Margot Robbie, Elizabeth Olsen, and Bella Heathcote sat on the same bench during the show. Epic front row, eh?

Both Rihanna and Lupita looked glamorous during the show, with Rihanna sporting a black, red, and yellow furry coat with thigh high boots, and Lupita wearing a burgundy top, a pink skirt, and a beige jacket.
