Megan Fox and Machine Gun Kelly have come "so far since last year"

A source told People: "Megan spent Thanksgiving with Colson and their daughter. They've come so far since last year."

MGK is making a concerted effort to "work on himself" and he "wants to be around for the baby".

The insider shared: "It was a much happier celebration this year. He's been making a huge effort to work on himself. He wants Megan to be happy. He wants to be around for the baby."

In October, a source revealed that the celebrity duo had been acting like a couple again, months after they called time on their romance.

The insider told People at the time: "They're together often, but he's going on tour soon.

"He spends pretty much every night at her house with the baby, and they act like a couple, but they haven't put a label on it or made anything official."

What's more, another source suggested that having a baby had brought Megan and MGK closer together.

The insider explained: "Megan's very happy with how he's stepped up for both her and the baby.

"While they still have separate homes, they spend a lot of time together as a family. They're putting the baby first, and it's brought them closer in many ways.

"Things are great now. He's amazing with the baby and she very much enjoys spending time with him."

Megan and MGK - whose real name is Colson Baker - met for the first time on the set of Midnight in the Switchgrass, the 2021 crime thriller film.

In January 2022, Megan took to social media to announce their engagement, and to reflect on the journey they've been through together.

In the caption, Megan - who previously suffered a miscarriage - wrote on Instagram: "In July of 2020 we sat under this banyan tree. We asked for magic. We were oblivious to the pain we would face together in such a short, frenetic period of time. Unaware of the work and sacrifices the relationship would require from us but intoxicated off of the love. And the karma."
