So much for bonding!
Nicole Richie was a recent guest on the New York-based chat show "Talk Stoop," where the show's host, Cat Greenleaf, accidentally slapped her in the face!
The slap happened just 20 seconds into what was supposed to be a fun four-minute segment about Richie's new scripted comedy series "Great News."
Greenleaf begins the chat by asking Richie what great news she's heard this week.
The actress, who lives in drought-ridden Los Angeles, says she's happy to hear it will be raining while she's visiting New York.
That's when Greenleaf goes in for a celebratory high-five and — whoops! — accidentally knocks Richie's sunglasses right off of her face.
Greenleaf, who regularly high-fives her celebrity guests, told TODAY she panicked when she saw Richie's glasses go flying.
"What were the chances? It was such a clean hit!" said Greenleaf, who jokes that from now on she may opt for "virtual hugs."
Luckily for her, Richie was "beyond a good sport."
"She was so gracious and kept things moving," Greenleaf said. "I caused her bodily harm! And she kept on rolling. She was a true pro."
In the clip, funny lady Richie sits in stunned silence after the high-five fiasco, but then breaks into laughter.
"I'm so sorry... I'm notoriously clumsy," a mortified Greenleaf says.
"I can see that," Richie jokes. "Out of my left eye only."
