The newly single heartthrob was on co-presenting duties with Gemma Cairney on Radio One this morning, and was happy to reveal his thoughts on the former The X Factor winner.
According to The Mirror, he said: "I do have a crush on Leona, she's hot! I have met her. She's hot. I haven't eaten dinner with her though."
And don't worry Directioners - Liam was keen to point out that he's still unattached, saying: "I'd like to highlight the fact I'm single. I am single!"
He added that "nice eyes, nice smile and good conversation" are what he looks for in a girl.
The teen star also revealed the reason for his new buzzcut. Explaining how the dramatic new do happened, Liam said: "I was doing a photoshoot for a certain magazine, and they said what can we do with your hair, and I was like, shave it off.
"We went shorter and shorter, and this is it."
In other 1D news, Zayn Malik has been spilling the beans on celebrity pal Justin Bieber. Taking over the Radio 1 co-hosting duties, Zayn chatted about Biebs on The Scott Mills show today.
"Justin called me yesterday actually - he's really cool," he said. "I wouldn't say I know him on a best friend level, but he's got lots of advice."
Best friends or not, it turns out JB even spent the night at Zayn and his girlfriend Perrie Edwards' house - where they splashed out on KFC.
Unfortunately Zayn wasn't so lucky when the 1D lads paid Justin a visit in LA.
He explained: "We went over to Justin's after the MTV VMAs and we just chilled out, and we were hungry and decided to cook noodles.
"He has a half pipe in the back garden and I thought it would be clever to go on it and I fell over and hurt my ankle. It was annoying, he was so good on it."
Earlier in the week, Zayn's bandmate Niall Horan compared the band's recent antics to an episode of The Inbetweeners.
