“It’s still early days but Liam is head over heels for Maddison. This has all the makings of a serious relationship,” the sources told New Idea. "He and Maddison have so much in common, they're having a great time."
While the couple has only been spotted in public on a few occasions, the insider said she's already met Liam's family and is planning to fly back to Australia for the holidays where the love birds will stay in his brother Chris's and wife Elsa Pataky's Byron Bay home.
"Chris has already give Maddison the thumbs up! To say they like each other is an understatement!"
Meanwhile, Liam's ex-wife and partner of 10 years, Miley— who has endured a series of ill-fated relationships post-split— is still doing everything she can to make him jealous, with insiders claiming her latest moves are all part of a calculated plan to get under his skin.
A source close to Liam recently told Radar Online that the "Slide Away" songstress is still obsessed with him and despite trying to prove she's moved on, is apparently still struggling to cope with the breakdown of their marriage and his new romance.
“She was drunk dialling him for a while, so now she’s resorted to social media to get his attention,” they said.
Another source close to Liam confirmed he's refusing to buy into her weak attempts to make him jealous, revealing he's over going back and forth with her and has no time for her petty games.
“This romance with Cody, supposed hospital visit and constant ‘look at me’ behaviour is all designed to push Liam’s buttons — and to be fair it’s always worked in the past because he’s a good guy who ultimately loves her.
"But now he’s just rolling his eyes and washing his hands of her, even as a friend, which of course is driving Miley nuts," the source continued.
While the rest of the world was shocked Miley was caught kissing Kaitlynn Carter less than a day before a representative from her camp confirmed she'd called time on her marriage with Liam, apparently, the Aussie heartthrob saw it coming. He is said to have known the musician was going to publicly flaunt her short-lived relationship with Kaitlynn, only to slap her new romance with Cody Simpson all over social media.
"Nothing is really a surprise at this point," a source told E! News. "He's leaving it all in the past and is in a different place now. He is busy on set and working. That's his focus now and what he is going to keep doing."
