Love is in bloom at an earlier and earlier age, Jennifer Connelly said last week on Late Night With Conan O’Brien. The 38-year-old actress revealed that her 11-year-old son Kai “broke up” with his girlfriend of two years last year, despite some surprisingly adult times spent “in a twilight between playdate and actual date.” On one such occasion, Kai and his “ex” were picked up by her mom after school. “I said, ‘What did you do?'” she recalled. “He said, ‘Well, we went to Citarella, we bought some groceries, we cooked a nice meal together.'”

Host Conan O’Brien — himself dad to Neve, 5, and Beckett, 3, with wife Liza Powell — said that he was “scared” by Jennifer’s story and doesn’t want his kids “to know about the opposite sex until their late 40s.” In agreement, Jennifer added that despite Kai’s burgeoning love life it is actually her younger son Stellan, 5, who makes her most “nervous.” She jokes,

Kai is Jennifer’s son with ex-boyfriend David Dugan; Stellan’s dad is Jennifer’s husband, actor Paul Bettany.
