Katie Holmes and Jason Bard Yarmosky put their summer romance on display in a sweet Instagram post Aug. 13, just one month after first stepping out together. In the picture, Holmes appears happier than ever, smiling in what appears to be a horse stable while sporting a white silk skirt set. The 47-year-old topped off her look with a set of silver, pointed toe heels and a natural style for her hair. Holmes and Yarmosky’s romance appears to be getting as hot as the dog days of summer, with the couple first stepping out last month for a screening of The Invite in The Hamptons July 10.
