Billie Eilish photographed kissing 31-year-old musician Jesse Rutherford

Music megastar Billie Eilish has been photographed kissing a new man on a flirty night out, with fans quick to point out the 10-year age difference.

Billie Eilish just confirmed her rumoured relationship with Jesse Rutherford by sealing it with a kiss Tuesday night outside an Indian restaurant in Studio City, Calif.

The Grammy winner, 20, and the lead singer of alternative rock band The Neighbourhood, 31, smiled as they shared a meal at Lal Mirch, which was followed by some adorable PDA on the sidewalk.

Eilish — who was dressed in an oversized denim jacket and black Converse sneakers — grabbed Rutherford’s face several times to smooch the frontman, who held his leading lady by the waist.

Rutherford, for his part, sported a long-sleeved, black-and-white striped shirt, which he paired with black pants and a matching tote.

His enamoured grin, however, was his most standout accessory, as he lovingly put his arm around the “Bad Guy” singer’s shoulder.

The new couple strolled for a bit while engaging in what seemed like flirtatious conversation before getting into Rutherford’s silver Volkswagen Beetle.

Eilish and her new beau first sparked dating speculation last Friday after being spotted at Universal Studios’ Halloween Horror Nights in Los Angeles.

An eagle-eyed fan captured a TikTok video of her reaching to grab Rutherford’s hand on their way out of a haunted maze.

Days later, Twitter account Pop Crave posted a photo of the two dining together at a restaurant.

The apparent romance drew mixed reactions online, with many voicing concerns over the duo’s 10-year age difference.

But others pointed out that the musicians have known each other for years. In fact, a Rutherford fan account shared a picture back in December 2017 that showed the pair posing playfully at a costume party — when she was 16 and he was 26.

The Everything I Wanted singer has remained tight-lipped about her love life over the years but has been linked to rapper Brandon “Q” Adams and actor Matthew Tyler Vorce in the past.

Meanwhile, Rutherford previously dated model Devon Lee Carlson from 2015 to 2021.
