When Cowell called in to On Air with Ryan Seacrest Wednesday to talk about the X Factor finale, Ryan asked if Carmen is Simon's new girlfriend.
"Girlfriend?" he said, laughing. "We're people who date," said Simon. "She's adorable, isn't she?"
Seacrest moved on to ask about L.A. Reid's departure from The X Factor:
"I'm going to miss him, because he's a good guy, but he has to go back and run the record label."
As for rumors that his replacement could be Chris Brown or Rihanna, Simon was much clearer with his response. "That is complete rubbish, absolute rubbish."
Ryan then asked if Lamar Odom has been to The X Factor? "Which one is she?" replied Simon.
Ryan then explained that Lamar is Khloe Kardashian's husband. "Well, there's so many" Kardashians, Simon said with a laugh. "Then the answer to that question is no, Lamar hasn't."
As for who will win The X Factor when a winner is crowned Thursday? "I genuinely couldn't guess at this point," Simon said.
