X Factor boss Simon is expecting his first child with girlfriend Lauren Silverman, while Louis' mum Johannah is pregnant.
Chatting with reporters in the US this week (via People), expectant father Simon said: "I was just texting with Louis Tomlinson last night because his mum is pregnant and is going to have the baby the same time as Lauren.
"So it's like, who is going to go first? I think I am going to win."
Simon also admitted that while plenty of things will have to change when Baby Cowell arrives, he won't be giving up his cigarettes anytime soon.
"There are a lot of boring things that happen when you have a baby. [You have to get rid of] sharp edges, cigarettes, alcohol … then there's [baby-proofing] the toilet. But I'll have a smoking room!"
Hmm, we wonder what Lauren will have to say about that!
Simon did admit on America's Arsenio Hall Show recently that he would try to quit for the sake of his unborn child.
The music mogul has been busy on the US version of X Factor but found time to film a video message for the UK edition at the weekend. Simon appeared via videolink to tell the remaining contestants that they'd all made the Live Tour!
"You've got to be focused, you've got to be amazing and you've got to sell millions of records. Good luck," he said.
Abi Alton was eliminated from the UK show last night after she landed in the bottom two alongside Hannah Barrett.
Although Simon isn't serving as a judge on the current series of X Factor UK, he has been keeping a close eye on the progress and hasn't been afraid to tweet his feelings on the judges' decisions.
When Miss Dynamix were sent home over Hannah Barrett earlier in the competition, he tweeted that he didn't understand the judges' reasoning.
