Talking to the Daily Mirror, Louis (who, according to ITV, still hasn't been confirmed as a judge himself) said: "It's between Mel B and Alesha. She's brilliant, isn't she? Watch this space."
Clearly not worried about his own fate on the show after Simon Cowell declared "it wouldn't be the same without him", the music mogul has certainly got people talking with his latest revelation.
And according to DigitalSpy, he has already backed his favourite for the final seat – "Mel would be my first choice, without doubt. I've always championed her both professionally and personally as I know she'd be fantastic - really opinionated and gobby."
Meanwhile, Simon has hinted to The Mirror that it would be possible for Alesha to jump ship to the X Factor, even though it would likely mean giving up her current role on Britain's Got Talent.
The BGT beauty is currently judging her third season of the show after previously sitting on the panel for BBC favourite, Strictly Come Dancing.
And like Alesha, Mel B is no stranger when it comes to talent competitions. Since offering her expertise on the Australian X Factor, fiery Mel has now followed suit stateside, joining as a judge on America's Got Talent.
With their judging skills under their belt, as well as their girl band stardom, its close competition! But which lovely lady will join Simon and the returning Cheryl Cole to take the remaining seat?
