Today Us Weekly brings word of a new romance blossoming on the shores of Brooklyn: Girls creator Lena Dunam is reportedly dating Jack Antonoff, guitarist for “We Are Young” band fun. There is Twitter proof and everything — Lena’s been posting pictures of Jack with Fiona Apple (back in 1997; don't worry, he's faithful). Also, Dunham “has asked to use Fun. songs on Girls," which sounds about right. Young, punctuation-happy love!
