Brian Austin Green reportedly "couldn't care less" about his ex-wife Megan Fox 's engagement news this month - though he is said to be "happy" for her.
Green, 48, and Fox, 35, were married between 2010 and 2021 - though were understood to have been separated for some time prior to their divorce being settled last year.
The former couple, who are both actors, now co-parent the three children whom they share together; Noah Green, nine, Bodhi Green, seven, and Journey Green, five.
Fox is currently in a relationship with musician Machine Gun Kelly, 31, - whose real name is Colson Baker. He proposed to her earlier this month whilst they were on vacation.
And although Green is said to be "happy" for his ex-wife, a source has claimed that he "couldn't care less" about her engagement news, according to Entertainment Tonight.
The source told the outlet that the actor - who starred on Beverly Hills, 90210 - doesn't have "any lingering romantic feelings" for Fox nor does he feel "any anger" towards her.
They added that there is "no bad blood or ill will between them at this point" - with both parties now in relationships with other people following their separation two years ago.
"Brian is happy for her, but it really isn't affecting him one way or the other," they said. The source added that Green primarily "feels indifferent" towards Fox's engagement.
Green - whose credits include Desperate Housewives and Anger Management - is however said to be "just glad they are co-parenting well together."
He is understood to be in a relationship with dancer Sharna Burgess, 36. The couple had been partnered together on the latest season of ABC's Dancing with the Stars last year.
Fox - whose breakout role was in Transformers (2007) - got engaged to her new beau Baker at a luxury spa resort in Puerto Rico earlier this month.
She later shared the news on Instagram, with her posting a video of the proposal alongside a caption that revealed that the location was special to the couple.
The actor - whose credits include Jennifer's Body (2009) and Teenage Mutant Ninja Turtles (2014) - said they had sat under the same tree in July 2020 and "asked for magic."

She added: "Somehow a year and a half later, having walked through hell together, and having laughed more than I ever imagined possible, he asked me to marry him."
"And just as in every lifetime before this one, and as in every lifetime that will follow, I said yes. And then we drank each other's blood," she concluded the recent post.
Baker - known as MGK - told fans that he proposed "beneath the same branches [they] fell in love under." He also said he designed the engagement ring himself, with the help of jeweller Stephen Webster, 63.
