They got pretty friendly on the magenta carpet — a little too friendly! Comedian Jamie Foxx and model Olivia Munn ran into each other at the Mayweather vs. McGregor fight in Las Vegas on Saturday, Aug. 26 and posed for photos together. But they looked a little cozy, so much that they sparked dating rumors — and we're pretty sure Jamie's rumored girlfriend Katie Holmes was not pleased.

Jamie, 49, placed his arm around Olivia's waist and held her close as they took photos before the sporting event. They were also extremely playful with each other — Olivia even pretended to give Jamie an uppercut to the chin in anticipation of the boxing match.

But even though they seemed to be flirty throughout their time together on the magenta carpet, eye witnesses told Entertainment Tonight that there was "nothing to it." Olivia, 37, arrived at the event by herself and she was posing for photos solo when Jamie stepped onto the carpet. She waved at him and photographers encouraged them to pose together — and that was it.

Even though this isn't the first time Jamie and Olivia have been spotted flirting with each other — they had a similar encounter at the 2010 Hollywood Domino Gala — it seems like it was an innocent exchange. Olivia seems to be fine on her own after her recent split from her ex-boyfriend, Green Bay Packers quarterback Aaron Rodgers, back in April.

And it seems like Jamie is still in a very private relationship with actress Katie Holmes. The pair sparked dating rumors when they were spotted at the 2013 Apollo In The Hamptons Benefit, and they have kept their love under wraps since then. But back in June, sources exclusively revealed to Life & Style that Katie, 38, is tired of keeping their relationship a secret and she was ready to go public with their love. "This is not at all how Katie saw her life going,” said an insider. “But she will take this over nothing.”
