Olivia Munn Reveals the Beauty Secret Behind Her Fake "Luscious Lips"

After people started speculating if the actress had some work done, The Newsroom star took to Instagram to shoot down rumors

Olivia Munn wants you to know the truth about her lips: They're fake—but not in the way you might think.

After fans noticed the 37-year-old actress' lips looked plumper, Munn took to Instagram to prove that her fuller pout was the result of her makeup—not injections.

Before heading to Tuesday's Runway to Red Carpet luncheon hosted by CFDA, Variety, and WWD, Munn documented her makeup artist Mary Phillips drawing on her lips. But after speculation of fillers started spreading, Munn put the rumors to rest by showing a video of her wiping off her lipstick.

"On my way to the airport so I gotta…bring down my makeup," Munn said in the video.

She also shared another photo of her on the plane via Instagram and wrote, "airplane glam (bye bye luscious lips).

Still, it looks like Munn didn't let any rumors spoil her afternoon. The actress was all smiles as she wore a yellow Veronica Beard ensemble along with bling by Jennifer Fisher Jewelry and shoes by Stuart Weitzman.
