The three posed for an official photograph by Mark Seliger and T.Swift posted the shot on Instagram, writing, "I feel like we achieved our goal of looking like we're in a new primetime drama series called Family Secrets."
Meanwhile, Lorde captioned the same image, "The Dreamers, last night at @vanityfair."
The Swift family recently got together in Florida to celebrate Austin and Taylor's dad, Scott Kingsley Swift, on his 64th birthday on March 5.Looks like March is a big month for the Swift family!
So without further ado, happy birthday, Austin!
