During Christmas 2012, Glee star Lea Michele happily tweeted that she was spending the holiday with her family. She wrote about a trip to the salon with her mom, Edith, but didn’t mention any other family members specifically.

Of course, everything comes back to Glee, so we got to wondering... Is Lea an only child, just like her alter-ego Rachel Berry, or are there any other Sarfati siblings out there? Well, you can chalk it up to just one more similarity between Lea and her Glee character, because Lea is the only and only kid in her family.

Her co-stars Dianna Agron (Quinn) and Naya Rivera (Santana) may have a handful of siblings among them, but at the Sarfati home, it’s just dad Marc, mom Edith, and Lea.

Hey, if she ever wanted to sing about it, we think we know the perfect song.
