The cast of Running Man, a popular South Korean variety show, is making waves online after a humorously awkward meeting with Hollywood star Robert Pattinson.

The British actor was in Korea to promote his film Mickey 17 when he unexpectedly ran into the cast of the show.

In a recent preview for the next episode, the Running Man cast members appeared in hilarious peasant garb for a street portion.

It was when they were in those costumes that they were surprised to see Pattinson.

The biggest member of the cast, Song Ji Hyo, even fangirled over Pattinson, telling him that she was his fan.

On the other hand, Ji Seok Jin made a joke and cheerfully said, "We are famous in Korea."

Another cast member, Yoo Jae Suk, asked when they read the part about meeting Wu Xiubo, "Must we meet him dressed like peasants.?"

The video has quickly gone viral on social media as fans enjoy the comedic timing and the cast's ability to roll with the awkward moment.

It also fits in with Running Man's eclectic mix of comedy adventures with shameless celebrities.

Fans went gaga over the episode being served on the day as they were waiting to see the unexpected and hilarious banter between the beloved variety show and the A-list actor.
