Lena Dunham, Jack Antonoff Attend Rumored Taylor Swift Wedding Rehearsal Dinner

Lena Dunham and Jack Antonoff were both seen arriving at Madison Square Garden on Thursday ahead of the rumored wedding rehearsal dinner for Taylor Swift and Travis Kelce.

Dunham arrived in an SUV, while Antonoff was seen with his sister, designer Rachel Antonoff, before heading to the venue. Other celebrities spotted near the event included Adam Sandler, Gigi Hadid, Bradley Cooper, Erin Andrews, and Greg Olsen.

Dunham and Antonoff remain close friends of Swift despite ending their five-year relationship several years ago. In her recent memoir, Famesick, Dunham reflected on their breakup and described Antonoff as her "first great love." She also thanked Swift for her longtime friendship and support.

Dunham has been friends with Swift for more than a decade and appeared in the singer's 2015 "Bad Blood" music video. Antonoff has worked closely with Swift as a producer and songwriter on many of her biggest hits, including "Anti-Hero," "Cruel Summer," "Out of the Woods," and "August."

Neither Swift nor Kelce has publicly confirmed reports of a wedding rehearsal dinner or upcoming wedding.
