When Robert De Niro met Tiffany Chen in 2015, their friendship was purely professional and he was still married to his second wife, Grace Hightower. They met while filming "The Intern," in which Chen played a Tai Chi instructor who is trying to teach De Niro's character. It wasn't a big stretch since Chen is a certified martial arts instructor.

According to Parade, her biography states that she has always been interested in movement and dance, learning ballet, hula dance, swimming, and gymnastics as a child. Chen won three gold medals in regional Figure Skating Competitions as well as several awards in France, the United States, and Vietnam.

When Chen got pregnant at the age of 45, she experienced what is considered a geriatric pregnancy. A geriatric pregnancy is one that occurs at age 35 or older, which sometimes causes complications. Yet, with her deep connection to movement and health, what happened to her after she gave birth to her daughter, Gia, took her by surprise.
