The two – currently on a European jaunt – are visiting London, where the actress recently purchased an apartment.
"This is the first time he's ever been here to see my flat," Dawson, 29, told PEOPLE Tuesday night at a London bash in honor of A-list hairdresser Tara Smith and her new line of environmentally friendly hair care products.
But that's not the only reason for their trip. "We went to France to see my boyfriend's family," added the actress. (Schreyer hosts a radio program in L.A. and goes by the name of "Mr. French.")
Sex TalkDawson was there to support her friend Smith, who worked on the Sex and the City movie. (The movie costarred Dawson's ex, Jason Lewis.)
So does she have any insight into a possible follow-up? She hasn't been approached, she told PEOPLE.
"My father was a professional bookie," Smith added. "And me being a bookie's daughter, I would put my money on them making a sequel."
