When asked in Cosmopolitan‘s October issue about her post-workout beauty secrets, Hudson’s humorously replied: “Shaving your head. Cuts down on time spent post-sweat.”
Hudson and Fujikawa made their red carpet debut in May after attending the premiere of Hudson’s mother’s movie Snatched in Westwood, California, together.
Romance rumors first started after the pair were spotted kissing during an L.A. lunch date in March.
Since then, the couple has been spotted all over the world. From going for a night out in N.Y.C. to celebrating Hudson’s birthday together in L.A., and even to Cambodia, where the couple took a trip together in June.
It appears Fujikawa fits right into Hudson’s hipster lifestyle. “Kate’s a free spirit who has always been attracted to musicians,” a source previously told PEOPLE. “But Danny also appeals to her because he is talented, bright and cosmopolitan like she is.”
Added the source at the time, “Kate’s enjoying herself. At this point it’s not serious.”
Marshall will hit theaters on Oct. 13.
