Model Cara Delevingne and music superstar Rihanna are making headlines recently thanks to their participation in a strange Paris fashion show March 4.

The 21-year-old model was part of a Karl Lagerfeld helmed fashion show for Chanel which took place in an unusual location -- the aisles of a fake Paris supermarket, and Rihanna was in attendance for the event.

However, according to Sugar Scape, Delevingne's confirmed girlfriend, actress Michelle Rodriguez, 35, may not be pleased with the singer's attendance at the show, as she has reportedly demanded Delevingne no longer associate with the 26-year-old Bajan beauty because she's afraid she'll swoop in and steal Delevingne from her.

"Michelle knows Cara has a crush on Rihanna and has asked her not to spend so much time with her, saying it's unhealthy and disrespectful to her," a source allegedly said.

"Cara is completely in love and listens to Michelle in all things. She has told her model agency to include her in all her plans too," the source added. "They are both jealous and possessive types and are living in each other's pockets."

Rodriguez may have nothing to worry about as Rihanna is allegedly rekindling her relationship with rapper Drake, even as reports surfaced that her other famous ex, Chris Brown, has once again broken up with Karrueche Tran for her.

A source reportedly told Hollywood Life that even though Rihanna and Drake aren't fully committing to one another yet, there's no drama between them as they continue hooking up.

"The only commitment they want is to be able to keep what they have and not ruin a good thing," the source said. "Neither of them are in a rush for anything. They are so chill and love what they've got."
