Rachel McAdams made her presence known at the 2023 Gotham Awards on Monday night as she showed up in a clinging black dress.

The 45-year-old actress — who opted out of the recent Mean Girls reunion — was clad in a long-sleeved turtleneck dress with a plunging keyhole opening at the chest.

The Notebook star wore a stone-covered lariat necklace with the look.

McAdams, who hails from Canada, rocked a glossy black manicure and emerald rings on each of her hands.

Her frosty-highlighted hair was parted at the center, with cascading loose curls framing her face.

The silver screen siren rounded out the look with a pair of pointy-toe black heels.

She flashed her megawatt smile as she looked stunning in a full face of flattering makeup.

Attention was drawn to her sparkling eyes with lash-extending mascara and her cheeks were dusted with a pink hue.

At Monday evening’s ceremony, Rachel was nominated for Outstanding Supporting Performance for her role in Are You There God? It’s Me, Margaret.

She walked the red carpet solo, as she rarely makes appearances with her longtime partner Jamie Linden.

Rachel and writer Jamie were first linked romantically back in April 2016, but have kept their relationship extremely private ever since.

They have yet to make their red carpet debut as a couple and don’t often appear out in public together.

The dazzling event was held at Cipriani Wall Street and saw stars like Bradley Cooper, Margot Robbie, and Penelope Cruz step out dressed to the nines.

The Gotham Awards typically kick off the awards show season and the production can be enjoyed on YouTube.

2023 marks the first year the show removed the decade-old budget cap, which only honored films that were made for $35 million or less.

In August Jeffrey Sharp, executive director of The Gotham Film & Media Institute, announced that this season he’s ‘excited to include more voices from around the globe by expanding eligibility for the many brilliant international films and filmmakers who deserve to be in consideration.’
