It's not even Halloween yet, but the award for best costume ever already goes to the one and only Liv Tyler!
Dressed as a "bun in the oven" — literally an oven with a bun baking inside of it — the costume is a cheeky reference to all those pregnancy rumors that ran rampant last month. The 37-year-old eventually confirmed the news that she was expecting her second child with a statement made through her rep.
"Halloween school dance. My favorite party!!!!!" she captioned the above photo, which also features her 9-year-old son, Milo — whom she has with ex-husband Royston Langdon.
Liv is expecting the child with her current boyfriend Dave Gardner, who just happens to be David Beckham's BFF! He has two children of his own with ex-wife Davinia Taylor.
