First of all, who exactly is Finneas O'Connell's girlfriend? Well, as it turns out, she's pretty famous in her own right. Diehard YouTube fanatics will more than likely recognize the name Claudia Sulewski. The 23-year-old is a beauty vlogger who's been churning out YouTube videos since 2009. Sulewski's since expanded to Instagram, too, boasting more than a million followers.

Sulewski's relationship with O'Connell can be traced back to 2018 when she posted her very first Instagram photo with the pop hitmaker. Since then, the two have been pretty much inseparable. In fact in 2019, O'Connell gushed to Buzzfeed about writing a song dedicated to Sulewski. "I wrote the song 'Claudia' about Claudia the day that I met Claudia, and I sent it to her the night that I met Claudia." A bit repetitive, but we're swooning, nonetheless.

Suddenly, in the summer of 2019, fans started picking up on something odd about Sulewski: her resemblance to Billie Eilish. As one Twitter user put it, "someone said Finneas' girlfriend looks like Billie and now I can't unsee it." Some were quick to brush off the gossip, but, nevertheless, chaos ensued in the Twittersphere. However, regardless of what the Internet has to say, the similarity between the two ladies doesn't seem to bother any of the three parties involved. So, to each their own, right?
