Most Billie Eilish fans are familiar with the fact that she and her brother Finneas are pretty close.
That's why a lot of her fans find it odd that her brother is dating someone who resembles her quite a bit.
While many find it odd, there have been some that were quick to come to Finneas' defense.
The two have been dating since October 2018, so it's a bit odd why this is becoming a thing so suddenly.
