Hilaria Baldwin admitted that she’s having trouble explaining how close in age her two youngest children are. The 37-year-old fitness instructor previously revealed in March that she and her husband, Alec Baldwin, welcomed their sixth child, daughter Lucia, just five months after she announced the birth of their son, Eduardo "Edu" Pao Lucas. It didn’t take long for followers to note that she couldn’t possibly have had biological children that close in age to one another.
