Jack Antonoff stood by ex-girlfriend Lena Dunham after she revealed her health struggles and that she underwent a hysterectomy. “Beautiful piece,” the 33-year-old songwritter tweeted on Wednesday, February 14, alongside a link to 31-year-old Dunham’s emotional essay for Vogue. Fans took to the comments to praise Antonoff for backing the Girls creator, despite their high-profile split one month earlier. It was very drawn out,” a source told Us at the time of the split.
