Of course, there is always the off-chance they are from ex husband Lamar Odom, who had reportedly still been sending Khloe (and momager Kris Jenner) flowers last year despite the fact that Khloe had filed for divorce months prior.
Khloe never did reveal who her first bunch of Valentine's Day flowers were from, but she did post this pic of a second bouquet of love that she received with the caption "I fall more in love every single day."
So, who is it from? Check out the card and see for yourself.
Aw man, we TOTALLY thought she was gonna reveal a relationship secret, but alas, it was just Kylie. We should have known that the queen of cryptic posts would never just come right out and tell us who her secret Valentine was!
Either way, we hope Khloe had a great Valentine's Day.
