Hudson told Meyers on Tuesday that she isn't sure how Bingham got into stocks and that he will ask for stocks for his birthday.
"He wakes up, he looks on his apps and follows his stocks and he makes good money," the actress said, before noting that his favorite company to buy stock from is Foot Locker.
"He's got a great math brain, which I just can't relate to really in any way. But he's like this creative with a math brain, which I'm sure there's a lot of those out there. I don't know many of them, but my son. So he'll create, draw and drum and then he checks his stocks," she continued before stating that she can't wait to see what he does when he's older.
Hudson also discussed her other son, 17-year-old Ryder Robinson, and played a clip of the teenager imitating how she acts on Instagram when speaking to her followers.
"I would say he's probably the funniest in our family. So this is like every day for me. Nobody makes me laugh like Ryder and he just constantly makes fun of me," she said.
Hudson shares Bingham with her ex Matt Bellamy and shares Ryder with her ex Chris Robinson. The 42-year-old also shares 2-year-old daughter Rani Rose Hudson Fujikawa with her fiancé Danny Fujikawa.
Hudson recently announced on Instagram that she became engaged to Danny Fujikawa. The couple started dating in 2016.
