The 44-year-old Stranger Things star and the 34-year-old singer attended the Skin Cancer Foundation’s Champions for Change Gala at the Plaza Hotel in New York City on Thursday, and happily posed together on the red carpet alongside Sebastian Stan, Adam Schweitzer, Dianne Wiest and Katie Holmes. While the two didn't pose separately from the group, they weren't secretive about their relationship on Sunday in New York City, where they were snapped showing major PDA.
At the Skin Cancer Foundation event on Thursday, Habour looked dapper in an all-black suit, while Allen looked chic in a floral Marc Jacobs dress.
Harbour previously dated Fantastic Beasts star Alison Sudol, and according to multiple reports, the two split in August. Meanwhile, Allen was previously married to Sam Cooper, but their divorce was finalized last June. Allen and Cooper share two daughters together, Ethel and Marnie.
