Los Angeles, California - Billie Eilish may be dating musician Jesse Rutherford, going by new photos snapped of the pair.

TikTok user Jeneffer caught a glimpse of Billie Eilish leaving a haunted maze at Horror Night at Universal Studios in LA, hand in hand with someone.

Though the person's face isn't visible in the clip, users presumed she was holding hands with the musician Jesse Rutherford, mostly based on the leather jacket he was seen wearing in an Instagram Story posted the same night by Billie's brother, Finneas.

Rutherford is the lead singer of rock band The Neighbourhood and at 31, he's 11 years older than Eilish.

Not long after the TikTok was posted, Pop Crave tweeted a pic of the two artists out for dinner.

Twitter and TikTok users reactions to Billie Eilish and Jesse Rutherford ranged from excitement – "MY 2 FAVORITE SINGERS ARE DATING????????" – to repulsion – "Ew he knew her she was 15… ewwww."

The age difference quickly became a recurring theme in the comments, with some commenters finding themselves put off.

"i love jesse but it don’t sit right with me how she’s not even able to legally drink n he’s 31 no no no," one wrote.
