According to The Ashley’s Reality Roundup, the 44-year-old has allegedly fathered seven children — whose ages range from five to 25 — by five different women.
And one of those kids, a 23-year-old daughter, reportedly has a child of her own — making Matt a grandfather!

Amber, 25, has since responded to the report and opted to stand by her man — who she declared “a great catch.”

This isn’t the first time the reality starlet has defended her controversial relationship.
When fans blasted Matt for his past struggle with substance abuse, she stood up for him, explaining, “Me and [Matt] both have rocky pasts…I’m not an angel and there’s a lot of things we’re not proud of but people change and we’re in love.”
