Ashlee Simpson Rossis dealing with the realities of her son growing up.
Chatting withJennifer Hudsonon her eponymous talk show this week about what it’s like to have a teenage son, the “Pieces of Me” singer marveled at how her oldest, son Bronx, 14, is “so tall.”
“He’s like 5’ 9½”, he towers over me,” said the singer, 38, who shares Bronx with exPete Wentz. “He’s really chill, though, so I’m lucky for that.”
“He’s a good kid so far,” she laughed, adding, “stay that way, bro.”
After Hudson joked about her own son, 13-year-oldDavid Daniel Otunga Jr., and his changing voice and appearance, Simpson Ross noted that Bronx’s “voice is deep, he’s a young man.”
It appears that way to others as well, as she recalled a recent mishap that occurred during a night out at the movies with Bronx and husbandEvan Ross.
