As fans were quick to point out in the comment section, an apple means something extremely important to GG fans: It's a food that Lorelai craves only when she's pregnant.
And considering that Rory and Lorelai eat complete trash 24/7, the fact that an apple is in the photo — and that it is specifically called out in the caption — seems pretty damning.
It could mean that Lorelai or Rory — her mom definitely could have passed down that apple gene — is pregnant.
However, as other commenters have pointed out, the photo could just be a callback to the Season 1 episode where Lorelai plays host to Rory's classmates before the Bangles concert...and where she uses the exact same language that's in the Instagram caption.
