Lizzo confused a 'Late Night With Seth Meyers' writer for Paul Rudd before she even had any alcohol in a new day-drinking video

• Lizzo confused a "Late Night With Seth Meyers" writer for Paul Rudd during a day drinking segment.
• "Tell me this ain't motherfucking Paul Rudd!" Lizzo said to the masked man.

As Lizzo recently learned during a "Day Drinking" segment on "Late Night With Seth Meyers," sometimes the truth hurts.

While filming the segment with Meyers at a New York bar, the chart-topping singer asked a masked crew member if he was actually actor Paul Rudd, who has been known to surprise people by doing segments like Billy Eichner's "Billy On The Street."

"Tell me this ain't motherfucking Paul Rudd!" Lizzo said as a masked crew member walked over. "No, see! Even the way he's looking now! Paul Rudd would do this. You know he would do that."

Meyers promised the singer the man would return toward the end of the segment to reveal his identity.

"Here's what's gonna happen: when we're done day drinking, he's gonna pull it down, and we're going to have a close up on you," Meyers explained. "We're going to see her reaction to how much Paul Rudd — not Paul Rudd — looks like Paul Rudd."

After several more drinking games, including a variation of Truth or Dare, the crew member returned and removed his mask, revealing himself to be "Late Night" writer and "The Menu" co-writer Seth Reiss.

"You don't look anything like fucking Paul Rudd!" Lizzo shouted. "You do look really hot. You are handsome. You look Grecian. Greek god. He's giving me Greek god! You're a hater, Seth."
