Kate Beckinsale has spent all week celebrating her milestone 50th birthday, flooded with congratulatory messages from friends and fans alike.
All the attention has been on her and every single incredible photo from all of her glitzy, over the top festivities.
However, in her latest glimpse into the birthday celebrations, there is one thing distracting fans: a loved-up photo of the Underworld actress with a handsome mystery man.
Kate took to Instagram Sunday to share a slew of photos from her latest round of celebrations: an epic party full of drinking, dancing, plus feathers and glitter galore.
But, among all of the dazzling photos and videos where the star is surrounded by her friends (and even Demi Moore!) some eagle-eyed fans couldn't help but direct their attention at one pic in particular featuring someone who some are now wondering whether it's a new man in Kate's life.

The snapshot, which in contrast to the colorful others is in black-and-white, sees Kate sitting on a man's lap, his face partly obstructed by her hand – which has a stack of diamond bands on her ring finger – as the two look fondly at each other.

Kate was most recently linked to Moments actor Matt Atwater, who bears some resemblance to the man in the black-and-white photo from Kate's post.
Earlier this year, the two were spotted out and about in New York City, in some instances holding hands or with Matt's arms around Kate's waist. However, there's been little to no updates on that front.
Before Matt, Kate was dating Canadian rapper Goody Grace, and was also romantically linked to fellow stars Pete Davidson, Jack Whitehall, and comedian Matt Rife.

Kate also shares a daughter, Lily Mo Sheen, 24, with ex-partner Michael Sheen, who she was with from 1995 until 2003.
