Savannah Guthrie's most embarrassing moment on TV came in the form of an uncomfortable question she asked Khloe Kardashian on the "Today" show.

Guthrie was joined by "Today" veteran Matt Lauer on Thursday night's "Watch What Happens Live" when a caller asked about her most regrettable moment on air.

"Khloe Kardashian was on and there had been these rumors that her father, Robert Kardashian, wasn't really her father," Guthrie told "WWHL" host Andy Cohen. "I didn't really wanna ask it because it was kind of probing and personal and intrusive, but I was new, and I felt like they wanted me to, so I delayed and delayed and delayed, and they were like, 'Five seconds, four...' and I was like, 'Is Robert Kardashian really your father?!' And she was like, 'Yes,' and I was like, 'And we're back after the local news.'"

After a game of "50 Shades of Lauer" -- where Matt admitted he's turned on by such things as role playing, cleavage, Halloween costumes and breaking news -- Cohen handed him a wig and asked him to recreate his infamous 2005 interview with Tom Cruise.

Enjoy the hilarious recreation in the clip below.
