The last time I saw Ted Lange post-Love Boat, was on a show in Chicago on the WGN station. He had wore a beard on that show. I'm glad he's doing okay.
I hear Maury Povich's voice as I look at those pics "Vin Diesel.....you are NOT the father" He doesn't have enough melanin to produce a darker child than he is with a WW.
I too thought it was weird his daughter is darker then he is but her face looks likes his ,especially the eyes and nose imo.
Genetics can be weird like that, plus, his wife looks asiatic and she could have dropped a little melanin into the mix as well.
