Robbie Williams Was Accidentally 'Rude' to Cher in an Airport by Walking Away Before She 'Finished Talking'

"Of course, I will think of this moment periodically for the next 25 years," said the Take That musician after recently meeting the "Believe" icon

If Robbie Williams could turn back time, he probably would've treated Cher differently.

In the caption of a post shared to Instagram on Monday, May 27, the Take That musician said he was accidentally "rude" to the "Believe" icon during a recent interaction before boarding a flight at an airport.

"Yesterday I met Cher. We were at the same airport terminal. Our mutual friend introduced us. My social awkwardness kicked in of course," explained Williams, 50. "I wanted to make the interaction as painless as possible for her. Looking for a natural break or ending in the conversation I made my excuses to go sit down. This was not for me but for her."

"Alas, I don’t think Cher had finished talking which made my exiting our brief interaction seem rude," added the "Angels" performer. "Of course, I will think of this moment periodically for the next 25 years."

Williams predicted he'll be "beating myself up at 4am" in the near future, thinking, "And remember that time you were rude to Cher?"

"As I was leaving, I blew a big kiss and said, 'Buy well and Barter, make sure you barter,'" continued the U.K. Music Hall of Fame member of the awkward chat. "Cher looked confused and I went to the toilet mainly to headbutt the wall, lamenting my stupidity."

Cher's certainly had more fruitful first interactions with fellow entertainers in the past. During an interview on The Jennifer Hudson Show earlier this month, the Grammy winner recalled her initial meeting with Meryl Streep before they costarred in the 1983 film Silkwood.

"I went to make a movie with her. I was packing my bag, and then I started unpacking it, and my sister kept packing it," recalled Cher, 78, at the time. "I went, 'I cannot go make a movie with Meryl Streep, OK?'"

"And then I get to Texas, and a woman comes at me with wide, white hair and a white dress," added the Rock and Roll Hall of Fame inductee. "She puts her arms around me, and she says, ‘I’m so glad you’re here,’ and it was her."

Cher continued, "From then on, we were joined at the hip. We’ve been friends all this time."
