While BAG was in Malibu tending to his broken-down car, Fox and her boyfriend, Machine Gun Kelly, were spotted getting cozy at a graduation ceremony in Los Angeles.
After spending close to two hours attempting to repair his vintage 1980 Jeep CJ5, the 47-year-old actor reportedly decided to call an Uber to take him home.
Though likely frustrated, Fox's ex seemed to be in relatively high spirits as he rocked a gray zip-up hoodie with white drawstrings, black pants and laidback sneakers.
Also in cozy attire was the 35-year-old Transformers star and her 31-year-old rapper boo, who towered over his "twin flame" at the outdoor event in the San Fernando Valley.
Megan sported a dark brown long-sleeve shirt atop gray drawstring sweatpants and white kicks. Her signature dark locks loosely framed her face.
As for MGK, the heavily tattooed musician sported a black long-sleeve shirt, dark gray cargo pants and black Converse sneakers. He wore a chunky pearl necklace around his neck and his platinum blonde hair up in spikes.
Earlier this week, the hottest couple in Hollywood spent the day at the Happiest Place on Earth. They were accompanied by Megan's parents – Gloria and Franklin – but her three sons with BAG were nowhere in sight.
It was an interesting move considering the actress' estranged husband has been parading his time with 8-year-old Noah, 7-year-old Bodhi and 4-year-old Journey all over social media lately.
Just last weekend, he collected major kudos from fans after sharing a photo showing his girlfriend – 35-year-old Dancing With the Stars alum Sharna Burgess – spending time with his kids in the pool. Green is also dad to 19-year-old son Kassius from a previous relationship.
While MGK – who has a 12-year-old daughter of his own – has met Fox and Green's kids, the Jennifer's Body star has accused her ex of "using" their children to make her look like a bad mom.
Green's major dad flex on Instagram came days after Fox was seen grabbing her rocker boyfriend's junk on the Billboard Music Awards red carpet.
Megan and MGK's super steamy and highly publicized romance got off to a strange start, as they were first seen holding hands last May, when no one knew she and Brian had split. Days later, the Beverly Hills, 90210 alum came clean about the breakup, and in November, he filed for divorce.
