It’s another boy for Donald Trump Jr. and his wife Vanessa! The couple welcomed their fourth child — and third son — on October 21st. Spencer Frederick weighed 7 pounds, 15 ounces upon arrival. Trump took to Twitter to share the news, as well as how his older siblings are adjusting, “Kai: dad I don’t want any brothers, I want to be the only kid! Me: Ok I will find you a new family where you can be the only kid! Kai: GRRRR.” Spencer joins big brothers Tristan Milos (1) and Donnie John III (3.5), as well as big sister Kai Madison (5), who may be starting to feel a little outnumbered!
