The 20-year-old was first spotted with Rutherford last month. A TikTok video caught the pair holding hands at Universal Studios' Halloween Horror Nights, and they were photographed at dinner together in Los Angeles shortly after.

The romance rumors stirred controversy online due to the couple's age gap. At 31 years old, Rutherford is 11 years older than Eilish.

But the Bad Guy artist is not letting the naysayers get her down as she shares photos and videos from her Halloween celebrations with her new beau.

In her latest Instagram post, Billie shared a series of photos from her Halloween festivities.

The post included a video of Rutherford dressed as a clown, as well as a photo of the pair's couple's costume that sparked significant backlash online when photos first emerged.

In an apparent clapback at critics of their age gap, Eilish dressed as a baby, while Rutherford dressed as an elderly man.
