Halsey and G-Eazy recently teamed up for their latest single, "Him and I," but their relationship isn't just professional. The couple first sparked dating rumors in August when Halsey referred to the 28-year-old rapper as her "baby" in an Instagram post, and even though they've kept mum about how their romance came to be, G-Eazy recently told Paper magazine that they met at a party. Aside from performing together, the couple also take the cutest pictures together and say the sweetest things about each other. In fact, G-Eazy says he and Halsey relate on "almost every single level." "We could talk for hours endlessly. She's been through a lot in her personal life, in her professional life," he explained. "It shocks me all the time that she's as young as she is, because even I'll forget sometimes and think she's my age and forget that she's five years younger." Halsey may only be 23 years old, but love knows no age.
