David Harbour and Lily Allen‘s intrigue is red carpet official.

The singer, 34, and Stranger Things performer, 44, stepped out together on Thursday evening to attend The Skin Cancer Foundation’s Champions for Change Gala at the Plaza Hotel in New York City.

Allen wore a high-neck floral-patterned dress star three-quarter sleeves and a pink ribbon around the neckline. She finished the look in black boots and a duo of hoop earrings, with her whisker restrained half-up.

Harbour ogled jaunty in an all-black suit with glossy joining shoes as he posed for draws alongside his date and other superstars like Katie Holmes and Sebastian Stan.

Harbour — who previously dated Fantastic Beasts star Alison Sudol — and the “Not Fair” hitmaker firstly inspired dating rumors in January 2018, when they attended the BAFTA Tea Party together.

They were spotted together this past August while he was filming Black Widow in London, where they attended the performance of The Lehman Trilogy at the Piccadilly Theater and then dined at a restaurant, according to E! News.

Following his hosting introduction on Saturday Night Live this past weekend, the Hellboy actor was photographed heading to the show’s afterparty in New York City with the British singer.

Allen shared photos from Harbour’s SNL sketch parodying a SoulCycle class, during which the host wore a sleeveless shirt and pictured off his muscular appendages. Allen captioned a zoomed-in photo of Harbour’s bicep, “Mine.”

The duo was then snapped locking lips as they stepped through wall street of New York City the next day to grab lunch together.

Allen, the sister of Game of Thrones Emmy-nominated performer Alfie Allen, revealed in January that she had split from her DJ lover Meridian Dan. The two had been together since 2015.

She was previously married to builder and painter Sam Cooper. They married in 2011 and announced their split in 2016 before finalizing their divorce last-place June. Allen and Cooper, 41, share two daughters: Marnie Rose, 61/2, and Ethel Mary, 8 next month.

In her latest Instagram post last week, Allen affirmed she was “Leaving UK till after Brexit. Good Luck Kids.”
