Tinsley Mortimer moved on quick from one nightlife guy to an other. After the socialite and Ains worth partner Brian Mazza split last month, we spotted her making out at Riff Raff with club partner Hari Kalyan Tuesday night. Pretending to be Kalyan, Mortimer texted us, “Yooo. Great seeing you tnite [sic]. Do you know a girl named tinsley? I’m actually dating her. I don’t want anything written about her. Cool?” Kalyan explained, “I didn’t send that. So sorry. They took my phone,” and added that attention-hungry Mortimer sent us the message. According to a friend of Mazza, “He left her because she’s too into society . . . the party scene was like a third person in their rela tionship.” But Mortimer told us, “I just met Hari last night . . . He as a friend texted you to be nice to me . . . we are not dating.”
