Liza Minnelli hit the Oscar red carpet in blue — from head to toe, almost (she opted for black shoes).

The actress, 67, sported a cobalt blue pants suit, and she accessorized with a streak of blue in her hair.

Twitter blew up with reaction, ranging from "wow" to references to Smurfs.

Judy Garland's three children — Liza, Lorna Luft, 61, and Joey Luft, 59, — are expected to reunite at the 86th Academy Awards, according to The Hollywood Reporter, to help commemorate the 75th anniversary of their late mother's most iconic film, The Wizard of Oz.

Ellen DeGeneres made a crack at Liza from the stage with her Oscar opening monologue. "That is one of the most amazing Liza Minnelli impersonators I've ever seen. Good job, sir."
