Now that they're both single, Liam is making it clear that he is 3,000% into her.
Leaving a comment on her photo on Instagram, he wrote, "wow" on her lingerie pic.
“The next Cheryl,” one fan even wrote.
But one person isn't shipping this potential relationship, and that's Kourtney's ex and baby daddy Scott Disick.
“Scott feels a tinge of jealousy over Liam’s flirty comment with Kourtney, but he knows he has no room to say anything to his ex,” a source revealed.
“So he’s going to keep his mouth shut about it. Scott has always thought Kourtney was really attractive but when a big celebrity reminds him of how sexy Kourtney looks, Scott takes notice. While Scott is in love with Sofia, he still has a lot of love for Kourtney, too, so he feels territorial and protective over the mother of his children.”
As for Kourtney, well, she's interested.
“Kourtney thinks Liam is really cute,” another source revealed, “and is totally open to going on a date with him. If he asked her out, she would say yes. Kourtney loves international guys, loves Liam’s music, and thinks he is sexy too.”
MAKE IT HAPPEN LIAM!
