Donna also has a grandchild out there that she never speaks of as well.
By then, Jennifer Gareis had taken over the role.
Upon her return,Donna fell for and married Eric Forrester, but his children didn’t approve.

Where is Donna and Justin’s son now?
Like many soap characters,Marcus had a dramatic lifewhile on “The Bold and the Beautiful” canvas.
He then had a one-night stand with Amber Moore, which produced a baby girl named Rosie.

Soon after that, he married a young woman named Dayzee Leigh and got custody of his little girl.
Marcus moved toSouth Africa for a job in 2013, with Dayzee and Rosie eventually joining him.
We can assume Donna keeps in touch with her son and granddaughter off-screen in scenes the audience never sees.

Maybe Marcus could help Justin put his life back together if he were to return.
