Taylor Swift penned a heartfelt handwritten letter to Lily Allen's daughter. It's truly an amazing gesture.

What's even more special is that Taylor, who is 33 years old, wrote this letter on elegant stationery. Lily Allen, who is 38, wasn't actually present when Taylor wrote the letter to her daughter. Instead, Lily's husband, David Harbour, who is 48 and known for his role in Stranger Things, shared the story while promoting his new movie Gran Turismo.

In an interview conducted before the WGA actors' strike began, David, who is a caring stepfather, revealed that he took one of Lily's two daughters to Taylor's Eras tour in Minneapolis. Lily has two daughters, Ethel (12) and Marnie (10), from her previous marriage to Sam Cooper.

During the Happy, Sad, Confused podcast, David explained how the experience unfolded: "It was quite extraordinary because I did mention as we entered the venue, 'If there's a chance to say hello,' I thought, 'Please, let it happen.' They informed us that Taylor would be leaving right after the concert, so I thought, 'Oh well, maybe not then.'"

He continued, "We enjoyed about 30 minutes of the opening act, and then a lady appeared with a letter."
